I laugh at you people talking about your car's falling value. Cars are not investments! Well, a few of them are, but they are only bought by millionaires and they cost many hundreds of thousands of dollars. The corvette is a sports car that is meant to be driven and enjoyed; if you worry so much about "value" then maybe you should sell your car and invest in mutual funds. For any buyer out there right now, the c4 is a tremendous performance "value" for the buck right now, the car was way ahead of its time in terms of its power and handling, this means that many more people can afford to buy one and enjoy it, which means more people joining the corvette owners club. That can't be a bad thing!
But on the negative side, the newest c4 is now thirteen years old, and requiring major repairs. One of my biggest pet peeves on my old c4 was that I couldn't find decent carpet or seat covers anywhere, the carpet I bought from a forum vendor got all wavy and bumpy in the rear hatch area, very cheap and tacky, AND it was the expensive mass back too. The new seat covers I bought were worn on the bolsters in less than three months. Some vacuum lines under the hood haven't been made for years, so you'd better not break any of the brittle ones. The aftermarket body side molding on the 84-90 looks terribly cheap, I was ashamed to put that on my car and sent it back to the catalog guys. And add to that the questionable life span of oem parts for a c4 (radiator, alternator, a/c compressor) and design flaws (perpetually leaking intake manifold gasket, troublesome EGR system) and you have a car that requires constant maintenance. And add to that the fact that there is no incentive for parts companies to manufacture quality parts for a 13-25 year old car, all they do is offer a replacement warranty; who wants to replace an alternator every three months or a power brake booster once a year because the stupid diaphragm inside the housing keeps breaking?
Leaky heater core by 100,000 miles is almost guaranteed, and that thing is a bear to replace. And why can't you get a quality water pump for a c4, my stock one lasted to 50,000 miles but then I had to get three replacement ones. Where does one buy quality parts, if they even exist? The stock radiator, same thing, the tanks are bonded to the side, and easily leak after 30,000 miles. Yeah I know, 30,000 miles but you should never have to replace it even once. And that stupid leaky shaft seal on the a/c compressor, if that isn't the most perfect example of a design flaw.
I guess I'm getting off base here, but I still maintain that the c4 is an excellent driver's car, it is poised, balanced, handles very well, and has more than adequate power even for today's driver. But the labor and money to keep it running finally drove me away from my beloved c4s, my c6 is ten times more reliable. If I were a millionaire I would probably have a c4 again, because then I could finally afford it.
