C5 Changes from year to year
Hello all! I will be purchasing a corvette in the near future. I was just wandering where I could find some info on the changes made from year to year on the c5's (preferably between 2000+). I'm not quite sure what year vette I should get. It seems that anything prior to 2002 seems to have many problems. Appreciate the help, thanks!

That's great you are buying a vette! These cars are wonderful. I hope you don't have any young male neighbors because they will be over all the time when you are out waxing. I know my 7 yo neighbor is over all the time helping me wax my "banana" (my MY vette) They just love these cars! Enjoy your self. All vettes are good but I would get a C5 2002 or later.

Looks like I'll be after a 2002 if cheaper than 2003. Probably not getting z06 and there doesnt seem to be too much difference between those years. Thanks for the info and the links.

You have to admit Chuck that you did phrase your post in a way that begs to be commented on... 7 yr old male came over and waxed your "banana"?
But I understand you didn't mean it at all like that.

The two slots of a 1998 (and possibly late 1997s) curve toward the rear at the bottom. (versus straight down)
I'm confused, what slots are we talking about here?

Great list!!!
For 2002, you should add these facts:
Aluminum automatic transmission cooler case (all models)
AM/FM stereo with in-dash CD player now standard on Coupe and Convertible
AM/FM/Cassette only available with 12-disc CD changer on Coupe and Convertible
You should also mention the 2003 anniversary and 2004 Commemorative Editions in your list.
Otherwise, your list is definitely the most comprehensive, all in one I've seen.

I haven't got a clue either. Maybe someone will chime in with the answer. Thanks for pointing it out.
