Hillbullies driving your car

well today somebody wanted to buy the mitsubishi. Well i let him test drive it. Well to make a short story even shorter, he overrevved it nd lets say its not running like it used to. he also wanted to look at the subaru, he looked at it before he mitsu. The clutch is crapped on it and he thought he could fix it. Well he made it even worse. Im surprised he didnt pull out duct tape. Now im pissed and trying to track is arse down.
