If the build sheet is to be believed then by simply checking the build date that would determine when the car was built. June 28 is very late in the production run considering that in 1996, for example, the production run ended June 15 for that year. Also as a member stated, GM stopped production runs before July 4th since they stopped production for two weeks before starting the next production year. I have not seen any 1990 zr1's later than mine that are around. I heard of a red/saddle 1990 zr1 with vin 3032 somewhere in alabama. I have never seen or heard of any cars over 3032 and neither has GM archives since they should no record of anything past 3032. I have to believe the build sheet because it also states where it was delivered too. 6/28 is very, very late production date for a 1990 zr1. Mine was sent to a dealer in Morristown, New Jersey. If anybody has a production vin older than #3028 I would love to know. Thanks.

I never mentioned anything about a build date, just the build sequence number and how the car could be built of sequence to that number.
Build date is another question, it all depends on where in the plant the car is considered built? When it rolls off the assembly line, rolls onto the dyno, its rolled out of the plant. No matter though, it would be consistent throughout the model year. There's going to be a few after your car, based solely on VINs.
1990 ZR-1's used VIN's 1G1YZ23JxL5800001 through 1G1YZ23JxL5803049.

I used to work beside the online VIN printer, access to it was limited.
