Ken Block, famous rally driver, started his rally career in his late 30s. Yes, he had money, connections and access to the best teams. But you could easily buy a second hand car for a few grand, tune it gradually, do courses and practice, practice, practice. You should carefully choose your speciality: rally, race tracks, drifting or just regional events (where entry can be as low as 100 eur). So your only disadvantage are the expenses. But they aren't as bad as you think they were.

Gentalman Racer is generally open to anyone with tons of money to blow(Ken Block founded DC shoes along with being a successful athlete before moving into motorsports). DHH is a sports car racer, including driving at Le Mans a few times.

"a few grand" won't get you into world class motorsports, but if you also have the space for a garage, trailer, and tow vehicle it is enough to be competitive at the club level. SCCA, NASA, PCA, and BMWCCA have club races all over the US.
