Hey guys, I don't remember anyone saying 19yr olds are x, y, or z. But then again, some of us owners are "older" - but we still enjoy "playing" and tuning our cars.
I still remember when I was 19 - just.
I had destroyed my Skyline RS, and was driving a nasty GM car.
The one thing I did that was smart at age 19 was do an advanced driving course. Learning that I was not the best "Fangio" on the road was the best lesson/reality check, then actually learning how to drive and survive was fun and invaluable.
Old guy getting off soap box...
