Don't waste your money on an 84 Vette....try to get at least an 1990.....but if you can stand the terrible ride ( even without the Z-51 )..then don't pay more than $5,000 for one...look on ebay ...lots for sale avg price $3,500-5,000....the reason the prices are so low is because it is a crappy car in every respect...items that are crappy..window lifts,dash,crossfire,fit,finish,RIDE..paint clear coat is rotten,seats rip apart,rattles & squeeks that you never eliminate..
There are people that will try to convince you it is a collector car....it is not it is a piece of crap.
