Ken Garff Volkswagen

I purchased a 2010 Jetta from Ken Garff Volkswagen just over 5 months ago, a purchase I have been regretting since the day after. The car I purchased had a few minor issues including a "rattle" that I was assured would be taken care of at the time of sale. After waiting for nearly three hours for a "complete inspection" I drove the car home. Not a week later the rattle had not "gone away" as I was told and I had the wheel bearings replaced. Needless to say that was not the issue either. Then the wheels and tires, then a $12 dollar clip that cost $170.00 to "diagnose" and install after I had paid for a diagnosis at another repair shop and told them it needed replacing. Now I find out the rattle is the whole front end is near falling off and it will cost me another $1,500.00 to repair. The service department is only just short of hostile with the attitude that I should have bought the nearly $50.00 a month warranty if I wanted my car to run. This is on top of the fact that any time I turn left the oil alarm is activated. The diagnosis I got for this would be it would take 5+ hours to figure out what the issue was and there was not enough time. aargh!
