Car values probably no one can predict. I went to an auction last weekend and I was surprised at how low the bids for some cars were. I think the auctioneers were also a bit disappointed. 400hp, fully refurbished muscle cars that could barely make $25k.
They sold a 60s VW Beetle where the guy apparently spent tens of thousands for $16k or so. Personally, I don't see these cars being worth anything extraordinary anytime soon. People just seem to prefer muscle cars, and European sports cars.
Persononally that's why I like them. You can get a nice running classic car for a decent price and the maintenance won't break the bank. Dont get me wrong, I don't think these cars will depreciate a lot either. You just won't be buying a house with one soon. Yours with the low miles, keep it in good shape, drive it now and again, and if you are lucky you will probably get back what you put into it plus inflation. That's a lot better than any new car. I might be wrong, just my opinion.
