You've got the dichotomy disease. There is no need to go to either extreme. You can belong to a country club and still live within your means. You can certainly drive a fast car and live within your means. Fast cars can be bought for well under $10k, especially in California where a fast car can last for thirty years and more without rusting. Most of the stuff on more expensive cars is just bling, or comfort features…
Anybody can buy a fast car, but few can actually afford to maintain it. A $10K fast car you buy might cost you a good bit of money per year to drive and keep in shape. Especially when it's thirty years old. That's mostly the reason it's only $10K to begin with (and the fact that the market for impractical cars is not too large).
sure if you buy some unreliable piece of crap...but there are plenty of fast cars that only require regular oil changes to keep in shape.
granted there are different definitions of fast, some people are fine with 14 second cars, others need 12s...and others don't consider anything fast that doesn't run 10s.
But overall, $10K is plenty to get yourself a reliable 6-7 year old car that's quick/fast.
