Buying a used car from this dealership has been on...

Buying a used car from this dealership has been one of the worst decisions I have ever made. I purchased a 2005 4Runner wholesale and after two days of driving the engine starts to misfire caused by a bolt stuck on an intake valve on cylinder 4. The dealership agreed the bolt could have been one of the two wire harness bolts left off the vehicle while their technician was attempting to repair a coolant leak. Taking the cheap route, they replace only the valve components where the bolt was stuck instead of properly diagnosing if that bolt had caused more damage. I pick up my vehicle with the same loud tapping symptoms and was told the noise would go away. Instead it got worse, much much worse. Letting the dealership handle the diagnostics this time, they find that there is massive internal engine failure: an intake valve on adjacent cylinder 2 had broken, lodged itself sideways into the head, and was causing damage to the piston head causing all eight of the exhaust valves to break off on the opposite engine head. I was informed that the engine failure had no relation to the bolt being left in the motor. I disagreed as these motors are indestructible and never have this kind of damage just by chance. After some legal issues, lots of personally paid towing fees, unprofessional phone calls, and failed negotiations I am now stuck with a useless vehicle, a blown motor, and 5 months of not having a reliable vehicle. This dealership is obviously not in the customer satisfaction business and I will inform everyone I know of my horrible experience with them.
