Buy a first-generation NSX with proof of timing-belt service and a clean bill on the aluminum body. Hidden accident repair on aluminum costs more to put right than on steel, and a magnet will not find filler.
For this November 5, 2026 guide, I checked the MotorTrend NSX buyer guide and the Car and Driver 1991-2005 NSX guide. So, the checks below come from those sources, and the paperwork section covers U.S. title steps.
Inspect the aluminum body in daylight
MotorTrend notes the NSX is mostly aluminum, so a magnet will not find filler, and aluminum structures rarely return to original after a hard hit. Inspect panels under good light and check gaps around fenders, hood, doors and trunk. Poor fit is a reason to ask for repair records.
Demand timing belt and water pump proof
MotorTrend says the timing belt and water pump should be replaced about every 90,000 miles, or 105,000 for the later NA2. Car and Driver gives a similar 90,000-mile figure. Without proof, plan to do the job right away and price it into your offer.
Check the early five-speed range
Some 1991 and 1992 cars had a faulty countershaft bearing snap ring. MotorTrend gives the affected five-speed range as J4A4-1003542 to J4A4-1005978, with the number on top of the transmission. Car and Driver says the shifter should not move excessively under engine load, and that failures tend to happen early.
Confirm the drivetrain and model year
Car and Driver notes the six-speed replaced the five-speed in 1997 along with a 3.2-litre engine, and fixed HID headlights replaced pop-ups in 2002. Make sure the car matches its claimed year and specification. Mismatches need documentation.
Test suspension, brakes and clutch
MotorTrend says an NSX with clunks or rattles does not make sense and asks buyers to check clutch engagement and slippage. Car and Driver notes early cars wore rear tires quickly until alignment specs were changed. Ask the inspector to check alignment and tire wear.
Check windows and trim
Window switches and regulators are sold together and cost a lot, according to MotorTrend, though slow windows alone are normal. Worn pedals with very low mileage should raise questions. Rubber trim and moldings on early cars may need replacing.
Book the NSX inspection with a shop that has seen the model before, and ask for a written report with photographs from underneath. Agree in advance who pays for the visit and what happens to your deposit if the findings are serious.
Use the history report for the right questions
Read title brands, dated odometer entries and changes of registration state before looking at service entries. Compare those events with the seller file and ask about gaps; a NSX that sat for decades can show long silences that are normal, while a sudden mileage drop is not. The federal NMVTIS program explains its title, salvage and junk data role; it does not replace a workshop inspection. Our rollback detection guide helps you separate a recorded conflict from proof of a particular fault.
Keep ownership paperwork separate from condition
Match the seller name to the title and request a written lien release where needed. Our lien-release checks explains the paperwork sequence. Federal odometer disclosure rules are summarized at Cornell LII, though older vehicles can be exempt from some disclosure requirements, so the absence of a mileage statement is not proof of anything by itself. Our service-record explainer covers what a missing service entry can and cannot tell you.
Set the offer after the inspection
Ask for separate estimates for safety work, overdue servicing and cosmetic improvements. A hypothetical $1,500 repair reserve is only a planning example; it can be inadequate on an older collector vehicle. A seller PDF can be edited, so obtain your own report using the identifier stamped on the vehicle. A car without belt records or with uneven panel gaps should cost less or be left alone.
We are a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian. Recent advertised pricing has been about $5.50 guest, $4.50 member or $6.75 for a bundle; confirm the price and included reports at checkout. Buy the report before committing, then keep it with the inspection findings and signed sale documents.
Take your time with the panel gaps and paint, and compare both sides of the car. Repairs on aluminum need a shop that knows the material, so ask who did any body work.
