If you want to go fast but not spend a bunch of money, there is a little secret in the used car market known as the E36 generation BMW M3. These things are cheap...really cheap when you compare them to E30 M3, E39 M5, Porsche 911, MkIV Supra and various other overpriced modern classics. Find this 1995 BMW M3 offered for $6,500 near Los Angeles, CA via craigslist.
Why is the E36 M3 so comparatively inexpensive? I dunno. It could be the fact that the US version got a detuned engine that makes only 240 horsepower, or that interior quality looks like it was made in North Korea. However, the fantastic reflexes, superb braking, and sublime steering feedback more than compensate for lack of forward grunt.
