The last six digits begin at 100001 and run thru 126328, accounting for each of the 26,328 Corvette Coupes/Convertibles built in 1989. In addition to the 26,328 Corvettes that were built for commercial sale, there was an additional 84 ZR-1 Corvette’s but that were not sold to the public. Each Vehicle Identification Number (VIN) is unique to an individual car.
For all 1989 Corvettes, the Vehicle Identification Number was stamped on a plate on the inner vertical surface of the left windshield pillar visible through the windshield.
Used to calculate the characters in the serial number and gives it a single digit code that can be used to verify the serial number is legitimate. (Note: The Check digit number varies depending on each specific VIN number.)
I’m looking at a corvette that has a C4 body but it has a K in the ID number and is title as a 1989. It’s not the only one I’ve seen.
