Pre-purchase inspection checklist
The pre-purchase inspection a shop sells: five measured stations, a priced correction on every finding, plus the disclosure the federal Used Car Rule requires.
A pre-purchase inspection checklist has one column the maintenance version does not: the priced cost to correct each finding. The buyer is paying for that column. Below is the full checklist, a worked example on a diesel pickup showing how each correction gets priced, the time budget the flat fee has to cover, and the disclosure wording the federal Used Car Rule puts on the window.
Key takeaways
- Identity and history come before anything gets measured.
- Every finding carries a priced correction, because that is the deliverable.
- Recall work comes off the total and goes on its own line.
- Report condition and cost. Leave the buy-or-walk decision to the buyer.
What does a pre-purchase inspection checklist cover?
Station 1. Identity and history
| Line | What gets recorded |
|---|---|
| VIN, decoded | Year, make, model, engine, plant, from the number itself |
| VIN plate condition | Rivets, font, tampering, matching secondary locations |
| Odometer | Reading, and whether it agrees with wear |
| Open recalls | Campaign numbers from the free lookup |
| Title status branding | What the buyer's own search returned |
| Emissions equipment present | Every device the vehicle left the factory with |
| Aftermarket tuning | Programmer, deleted equipment, modified fueling |
| Service history evidence | Stickers, filters, dated parts, receipts in the glovebox |
Station 2. Evidence of prior repair
| Line | What gets recorded |
|---|---|
| Panel gaps | Measured where they differ side to side |
| Paint depth | Readings that differ across panels |
| Overspray | Under hood, door jambs, wheel wells |
| Fastener marks | Bolts that have been turned |
| Frame and rails | Kinks, welds, corrosion, repair sections |
| Weld quality | Factory versus somebody's afternoon |
| Water evidence | Silt in the spare well, corroded connectors, musty carpet |
| Airbag system | Lamps, module faults, replaced components |
Station 3. The measured inspection
| Line | What gets recorded |
|---|---|
| Brake friction, each corner | Millimetres, thinnest of the pair |
| Rotors or drums | Thickness against threshold, scoring, runout |
| Tire tread | Thirty-seconds at three points, each corner |
| Tire age | DOT week and year |
| Suspension and steering | Measured play, which joint |

Station 4. Road test
| Line | What gets recorded |
|---|---|
| Cold start | Cranking seconds, smoke, roughness |
| Acceleration | Power delivery, boost behavior, smoke under load |
| Braking | Pull, pulsation, pedal travel |
| Steering | Wander, vibration and the speed it appears |
| Transmission | Shift quality by gear, flare, harshness |
| Noise | Where it comes from and at what speed |
Station 5. The deliverable
| Line | What gets recorded |
|---|---|
| Finding | One row per condition |
| Measurement | The number behind it |
| Severity | Safety now, service soon, monitor |
| Correction | The operation that fixes it |
| Cost to correct | Priced at your labor rate and your parts |
| Covered by recall | Yes, with the campaign number |
| Photo reference | Every finding, without exception |
| Total cost to correct | The number the buyer takes to the seller |
What does a filled-in pre-purchase inspection look like?
A 2018 Ram 2500 with the 6.7L Cummins, 118,400 miles, inspected for a buyer looking at a private sale. This is an illustration and no line on it came off a real ticket. Inputs are stated: the posted labor rate is $165.00 per hour, the hours are illustrative, and the costs are illustrative supplier costs run through the bands in the parts matrix template.
| Finding | Measurement | Correction | Cost to correct |
|---|---|---|---|
| Steer tires worn | 5/32 inch both sides | Two tires, mount and balance | $1,181.80 |
| Front brakes low, rotors scored | 3 mm friction | Pads, rotors, hardware | $948.28 |
| Turbo actuator fault stored | Code active on road test | Actuator replacement | $1,532.28 |
| Coolant seep at water pump | Wet, crusted, no drip | Pump and coolant | $792.89 |
| Total cost to correct | $4,455.25 |
How each line was priced
| Line | Labor | Parts | Job total |
|---|---|---|---|
| Tires | 1.0 hour at $165.00 is $165.00 | Two at $328.00, each at 1.55, is $1,016.80 | $1,181.80 |
| Front brakes | 2.2 hours at $165.00 is $363.00 | $96.40 at 1.70, two rotors at $107.00 each at 1.70, $24.00 at 2.40 | $948.28 |
| Turbo actuator | 3.4 hours at $165.00 is $561.00 | $684.00 at 1.42 is $971.28 | $1,532.28 |
| Water pump | 2.6 hours at $165.00 is $429.00 | $148.90 at 1.70 plus $56.80 of coolant at 1.95 | $792.89 |
Set that total against the fee. At the time budget further down, the inspection is 1.5 hours of bay time, so a shop on a $165.00 posted rate quotes $247.50 for it. The buyer walks away holding a priced list many times the size of what they paid, and the seller either meets them in the middle or the buyer keeps looking. Either way the buyer got the number they paid for.
Then the second half of the business case. That priced list came from your shop, on your letterhead, at your rates. A buyer who goes ahead with the purchase has a job list already quoted by somebody they now trust.
What does the federal Used Car Rule put on the window?
The Buyers Guide, on every used vehicle a dealer offers. 16 CFR 455.2 states the duty:
"Before you offer a used vehicle for sale to a consumer, you must prepare, fill in as applicable and display on that vehicle the applicable "Buyers Guide" illustrated by Figures 1-2 at the end of this part."
The same section prints the alternative disclosure for states that limit as-is selling, and it is worth reading to a buyer who thinks a sale sheet ends the conversation:
"The dealer doesn't make any promises to fix things that need repair when you buy the vehicle or afterward. But implied warranties under your state's laws may give you some rights to have the dealer take care of serious problems that were not apparent when you bought the vehicle."
None of that is your shop's problem, and saying so on the report is the right move. Your document reports condition and cost. What the buyer does with it, and what rights they have against a seller, belongs to them and their own advisors.
Two free federal tools belong in station 1. The NHTSA vPIC service decodes a VIN into year, make, model and engine, which stops a seventeen-character transcription error becoming an inspection of the wrong vehicle. The NHTSA recalls lookup returns open campaigns for that VIN, and anything it finds gets taken off your cost-to-correct total.
What changes when the used vehicle is a work truck?
The thresholds stop being your opinion. Appendix A to 49 CFR Part 396 sets the minimum standards a commercial vehicle has to meet, opening with the sentence that governs the whole list:
"A vehicle does not pass an inspection if it has one of the following defects or deficiencies:"
On steer-axle tires it is specific:
"With less than 4/32 inch tread when measured at any point on a major tread groove."
A buyer looking at a truck that will run under a DOT number needs two totals: the cost to make it legal, then the cost to make it right. Those are different numbers, and separating them is what makes a commercial pre-purchase inspection worth more than a passenger-car one.
How long should a pre-purchase inspection take?
Budget it before you quote it, because the flat fee only works if the time is bounded. A workable split across the five stations on a light truck:
| Station | Time | What eats it |
|---|---|---|
| Identity and history | 0.2 hours | VIN decode, recall lookup, service evidence |
| Evidence of prior repair | 0.3 hours | Paint depth readings, panel gaps, undercarriage |
| Measured inspection | 0.5 hours | Wheels off, measurements, scan tool |
| Road test | 0.3 hours | Cold start plus a route with a hill and a highway |
| Report and pricing | 0.2 hours | Photos, findings, the cost-to-correct column |
That is 1.5 hours, which at a $165.00 posted rate is the $247.50 in the worked example above. Two stations run over on a regular basis. A vehicle with evidence of prior repair turns station 2 into a hunt, and a diesel with stored codes turns station 3 into a diagnosis. Decide in advance what you do when that happens. Either stop and quote the extra time, or absorb it and set the base fee high enough to carry the overruns, which means counting how often they happen on your own bookings before you pick the number.
The report station is the one that gets squeezed, and it is the one the customer is buying. A rushed cost-to-correct column with three findings priced from memory is worth less than an honest one with four findings priced from your suppliers.
Where do pre-purchase inspections go wrong?
| Failure | What it costs | The fix |
|---|---|---|
| Findings with no priced correction | The buyer cannot negotiate with it | A cost column on every row |
| A buy-or-walk recommendation | You own somebody else's decision | Report condition and cost, stop there |
| Recall work inside the total | The number is wrong and the buyer finds out | Its own line, with the campaign number |
| No photos | The seller disputes every finding | One photo minimum per finding |
| Inspection quoted hourly | The buyer will not commit on the phone | A flat fee, stated up front |
| Same form as a maintenance inspection | Prior repair and history never get checked | Stations 1 and 2 exist for this |
| No road test | Half the drivetrain findings are missed | Build the time into the flat fee |
| Report goes to the seller | You just did the seller's marketing free | The report belongs to whoever paid |
That last row causes more arguments than the rest combined. Decide in advance who the customer is, write it on the document, and hand the report to that person only.
How do you copy this checklist into a spreadsheet?
Two sheets. Findings on one, with the priced correction alongside. The header block on the other, because identity and history are what make the report a report.

What happens to the priced list afterward?
It becomes an estimate, and that is the step worth automating. Every row in the cost-to-correct column above required somebody to find labor hours for the exact engine, price parts at a supplier, then do the arithmetic. Four findings on a diesel pickup means four passes through all of that, and it happens while the buyer waits on the phone.
Mechanica builds that from the completed inspection. The drafted jobs land on the same repair order with the shop's own rate applied and every line showing where its number came from, so the advisor is reading a priced list instead of building one. A person still reviews it and decides what goes out.
The vehicle inspection checklist and form is the maintenance version of this document, and the estimate template is what the priced list becomes when the buyer says go. Multipliers behind the parts column live in the parts matrix template. For the vocabulary, see VIN decode and digital vehicle inspection. Every form a shop runs is on the shop forms roundup and the guides hub.

Questions shops ask
- What is a pre-purchase inspection?
- A paid inspection a shop performs on a vehicle somebody is thinking of buying. It differs from a maintenance inspection in what it hunts for: prior repair quality, evidence of collision or flood, open recalls, then a priced list of everything the buyer would need to fix. The output is a cost-to-correct number, not a recommendation to buy.
- What should a pre-purchase inspection checklist include?
- Identity and history first, then the same measured stations as a maintenance inspection, then two things a routine service check leaves out: evidence of prior repair, plus a priced correction for every finding. The buyer is paying for the last column, because that is what they take to the negotiation.
- How much should a shop charge for a pre-purchase inspection?
- Budget the bay time station by station, multiply by your own posted rate, then quote the result as a flat fee so the buyer can say yes on the phone. The time budget further down this page is where that number comes from. Price it below what the bay time costs you and you will resent the fourth one you do that week.
- Should the inspection tell the buyer whether to buy the car?
- No. Report the condition, the measurements and the cost to correct, then let the buyer decide. A shop that says buy it owns the outcome, and a shop that says walk away owns the seller's opinion of them. Numbers travel better than advice.
- Does a used car sold as is mean the buyer has no rights?
- It depends on the state. The FTC's Used Car Rule prints an alternative disclosure for states that limit as-is sales, and that wording tells the buyer implied warranties under state law may still give them rights to have the dealer take care of serious problems that were not apparent at purchase. That is a legal question for the buyer, and it is another reason the inspection report should stick to measurements.
- Should the inspection check for open recalls?
- Always, and it takes a minute. NHTSA publishes a free VIN recall lookup. Work covered by an open recall is done free at a dealer, so it should come off the cost-to-correct total and go on a separate line, which makes the report more credible rather than less.
- What is different about inspecting a used commercial truck?
- The thresholds are published. Appendix A to 49 CFR Part 396 sets the minimum standards a commercial vehicle has to meet, so a truck failing on lining thickness or steer-axle tread is not a matter of opinion. Price the corrections that bring it back inside those limits and the buyer knows what the truck costs before it earns anything.
- Does the inspecting shop usually get the repair work?
- Often, and that is the business case for selling the service at all. A buyer who has just paid you to price the corrections walks away holding a job list from a shop they now trust. Quote the work on the same document and the conversion follows.
