FIRST, I THINK U SHOULD HAVE TEST DRIVEN IT. THEN WHEN TH STANG REVVED, told him not to do anything., or when he was first starting to take u for the tes tdrive, tell him to go easy on it, u spent all that money on the car for it to drive like it does, and he (for free) gets to wnjoy it just like u? wrong. tell the supervisor/boss, if hes a personal mechanic, dont use him anymore.
