if the bumper was only 150 to fix you would have fixed it esp for resale puropse and seeing as you have had to put ALOT of money into the mechanical work, which doesnt make it sound like a perfect running car. these cars have issues all the time. sorry dood but you NEVER can assume people should pay you back for the money you have out into repairs. 166k, the car is worth 2800.00 to a blind man
