looks good as a 20 footer. If I bought it thats how it would stay. buy it for 3k and spend 5k restoring it and another 5k for paint and you have yourself a nice 8k car you paid 13 for. If you want a nice one shop around with 8-10k in your pocket. Better yet for the same money you can get a c4 that will eat it alive in every catagory. Ive had a couple c4s. both lt1s a 92 and a 94. They are even respectable in performance compared to new cars today. Probably one of the best bang for the bucks in a performance car today. 0-60 in the 5 second range, Top end of 160 and get 25 mpg all day long. Compare that to 8-9 seconds and a `120mph and 15 mpg in a c3 and the c4 will blow it into the weeds in the corners. only downside to a c4 for us old farts is there hard to get in and out of. you can pick up a nice one for 8k and one close to mint for 10. In my opinion some day there going to be appreciated and start climbing in value. heres an typical example https://chicago.craigslist.org/chc/cto/d/chicago-1992-chevy-corvette-quasar-blue/7309408166.html
As my cousin found out, when some thing breaks or wears out on a C4 and a LOT does, it costs a LOT of money.
IF one wants to go fast crate engines with three time the HP of a later C3 are comparatively cheap and come with 3 year warranties in many cases, plus chassis improvement parts are cheap and easy to install compared to the uni-body C4.
At this point in time C4s are dropping in value fast, and even C5 or C6 are available at what are actually dropping quicker than any ever expected.
One reason is they built too many compared to the small numbers of the earlier ones.
It all depends on what you want it for, go fast , or like my dork cousin, all show, no go.
