A used Nova is two inspections: an identity check on any SS claim and a rust check on the floors, cowl and rear quarters. On 1968-1971 cars the VIN does not encode the engine, so badges and a loud exhaust prove nothing.
For this November 5, 2026 guide, I worked from the Classic Cars Arena Nova guide and a Motorious rust checklist. So, the model specifics below come from the Nova guide, and the general rust method from Motorious.
Know which generation it is
Classic Cars Arena says the nameplate ran from 1962 through 1979. The first Chevy II ran 1962-1967, the second generation from 1968 to 1974 is the one collectors want, and the 1975-1979 cars moved to the X-body platform with a hatchback option. Price each generation on its own market.
Read the cowl tag first
The guide says to check the cowl tag riveted to the firewall, which lists body, trim and option codes. Photograph it before talking money. A seller who will not open the hood for the tag is a reason to leave.
Verify the engine by casting and suffix
For 1968-1971 SS cars, the guide says the VIN does not identify the engine, so you confirm it by the block casting number and stamped suffix code. It lists the L78 396 at 375 hp as the most desirable SS engine. Compare casting dates with the build date.
Probe the floors and cowl
The guide warns that Nova floors rot from the inside out because moisture is trapped under the carpet, and that water pools at the cowl seam at the base of the windshield. Probe floor pans from underneath at the seat mounts and transmission tunnel, and look for bubbling at the cowl.
Check rockers, quarters and rails
Walk the car looking at rocker panels, lower rear quarters and the rear valance. The guide also points to the rear frame rails where they meet the floor and the front subframe mounting points. A magnet run along the rockers can show filler.
Treat COPO claims as specialist work
The guide notes roughly 1,015 COPO 9562 cars were built in 1969 and says fakes outnumber genuine cars by a wide margin. A COPO claim needs specialist authentication, not a seller story.
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 Nova 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 rust-and-history explainer 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 odometer discrepancy guide 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 that cannot be seen from underneath is not ready for a deposit.
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.
Ask the seller for any restoration photos showing the floors and cowl before paint. Bring a cloth-wrapped magnet and a flashlight, and ask permission before lifting carpets or trim.
Book the inspection with a shop that has worked on this 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.
If the car has been converted from its original engine or transmission, ask for a parts list and receipts. A well-documented conversion can be a good driver, but it should be priced as one.
