Difference in bodys between years
Oh, and I think the exhaust tips changed after the first or second year. I'm not sure: hopefully someone else will chime in.
(I am not going to get into special color's by year, etc)
You can tell the 50th's (03's) by the badging..
You can tell 97-99's from the keyhole in the pass side and usually the wagon wheels (i believe the thin spokes were an option in 98 and/or 99?)
you can tell 01-04 z06's by the fixed roof and the brake ducts (03 z06 will have the 50th badge)
but the one car you can tell exactly the year by body is the 99-00 FRC. - basically because of the keyhole, but still a good fact to have.
When we were at carlisle - My buddy pointed out a Pewter Z06 on the field, and said jokingly to me "I thought they did not make a z06 in pewter" (I mentioned this a few times in the past to him as mine is 2000 FRC is pewter)
So I took one walk around the car, The guy had the registration for the show in the window and stated it was a 2002 Z06. It had the Z06 Brake Ducts, Z06 Exhaust, Z06 Wheels, Z06 (or painted) calipers, Z06 Seats, (the hood was closed so i could not go into detail with head numbers, etc..) I said - it is a 1999 FRC.
The guy did a good job with most of the stuff, but the car still had a) pewter paint, b) non z06 gauge cluster, and c) pass side key hole.

I just thought it was funny that one of the only C5 models that can be identified exactly to the year (body and features) and we found a poser. I hope someone did not sell him this saying it was an 02 Z.

I remember being told back in 1997 that the magnesium wheels where the standard wheel on export cars, but I can't confirm that with any information that I currently have. Maybe someone else can confirm/dispute that.
Of course if somebody asks I always say 98, never anything newer.



The 97's and 98's have the old style headlight adjustment plugs with out the key slot.
The '97' coupes do not have blowout clips on the roof panel (I think I recall)
The rear slots slant down a little more on the later model years (I think '01 and beyond.)
I know I'm missing some.
