Just my 2 cents on the issue of too young. When I was 17 I purchased my first new car, it was a 1970 Chevelle SS 396 and was just over $3000.00 dollars. Don't know what that would be in 2017 dollars but I was only making about $500.00 per month. Had a hell of a lot of fun with it, and at 17 that's all you are thinking about. I retired at 56 and I am still having fun.
