Vin number decoding
Hi All, Question for those more experienced with VIN decoding. The VIN on my C6 is 1G1YY34U755133707. If the fifth digit is a "Y" what model is that? I can figure out most of it, but some help would be greatly appreciated. Thank you!

"Y" is any model other than a ZR1. 6th character is a "3", which says the body style is convertible.

10 Model year designation from GM B = 1981, C = 1982,

Thanks. I bought this car a couple months ago and was not sure how it came from the factory. I have removed all the cosmetic changes the previous owner made. trying to get her back to original.
thanks again!

Cool! Love this car. Its is a hundred times more fun than every other car I've ever owned, corvettes, triumphs and even better than my 2019 Camaro. Just a pure joy to drive.
BTW, I noticed you commented about no reply from me...Sorry, I hate to admit this (but I will) I only get on this site at work, wink, wink.
I haven't been at work a whole lot lately, so.....
