I did scca auto-x for a few years. Never came close to being the fastest car there, but my car was just a humble 1st gen Dodge Neon. I usually had times in the middle overall, with high performance cars like subaru STI and also cars like miatas coming in ahead of me. I had a lot of fun, but it got boring since you only got 3-4 1 minute runs and spent all day in the hot sun. The cost and time commitment just wasn’t worth it. I’d rather go to a decent gokart track.
