Sounds like an awesome time for the OP! Would I buy that car after that... probably not. Was it revved hard on a cold start many times in its young life... yes. Are the tires gonna be cupped and need early replacement.. yea.
But,
Did it nearly sell the OP on a twin? Heck Yea! and if it does, then that salesman made himself a profit by beating up 1 used FRS out of 30,000+
Beating on cars is a glass half full kinda thing. Gives you instant gratification but in the long haul can be tough on the car. I agree it is sad some unknowing lady or gent may buy the car that was hooned for daysss.
Still sounds like fun and hope you join the community!
