Again someone who stops with this hobby because of money reasons

Yes it's a pritty expensive hobby, but as other ones said: just buy one car?
A little time ago I wanted to stop too, I had invested 2000+ euro (2800 dollar) in the last 2 years, and I'm only 15, that's a bit too much for a 15 year old kid IMO. But I'm glad I didn't sell stuff or something
