Blk Btty C5

i own an 04 c5 which i unfortunately have to sell, gettin a little pricey with all my bills

im lookin to pick up a 99 z28 i found and i was wondering if you guys could answer some questions for me

i dont know too much of a difference between the years of the f bodys, as in is a 00 better than a 99? etc

also i found a clean 99 with 87k miles on it for 7,800. stock with intake and catback auto.

is it a good price?

pretty much if theres any general knowledge i need to know about an fbody to watch out for or whats good/bad

anything will help thanks guys
