Car Hop Bought a car, that they will only half repair plus parts are from a scrap yard!!! omaha, Nebraska

Purchased a car from carhop. I realize these are used vehicles and wasnt expecting a new car. First the personnel were great as i had the car for a day and reported the brakes were crappy, the window wouldnt work and the car stalled at speed. The guy i bought it from was great. took my info and said to send it to the shop. No problem. After the mechanic looked at it, the diagnosis was a bad fuel pump. ABS sensor. And bad window regulator. Car hop wouldnt pay for the ABS. Guess a safety system for brakes is my problem. They would pay for the window and fuel pump. ok good..4 days later, parts still arent at mechanics..Called service and was told they would check with the scrap yard for the fuel pump..Scrap yard!?? Ive worked on many vehicles and scrap yards are great for many parts but getting a scrap yard fuel pump just isnt something a normal person would do. So my situation is this. Brakes will stop me but will not work like the car was designed to do. Ill eat that. Window is repaired. Great. The fuel pump they are installing since it came from a scrap yard, i fully expect to break down again in the near future where ill have to cough up the cash to repair or spend my time and money on fixing something twice that only one repair should have been necessary. Well live and learn. Sales personnel a+. Service is a bad rip off. Beware
