Stupid Murdock Chevrolet

So I am very upset with Murdock Chevrolet at this point. When we first got the car and test drove it Kellan said that it pulled to the left. Then we went in and signed the papers for the car and forgot to put that to be fixed as part of the deal for getting the car. The drivers side speaker was also out so they had to order a new radio to see if that would fix the problem. When I took the car in to get the radio installed, which by the way was like a week later, I mentioned to them that the car was still pulling to the left and to check it out. So they fixed the radio and said that the alignment was off. But it would be like $90 to do an alignment. We declined at the time thinking that it would not be that bad. Well 4 months later the cd player quits working and the drivers side tire is almost bald. So I take it back into Murdock to get the radio fixed again and come to find out they no longer make the radio for a 2005 and that we will always get a refurbished one. Kellan has me give his number to the guy so that he can talk to them about the tire and they say that since it was not part of the original deal that it was our problem. The guy that sold us the car said that he does not remember the situation and the service guy says that we could have hit a pothole right out of the dealership on the day that we bought it and so it could have been our fault. He also informed us that the tires were not the right size for the car and that we would not need 1 but 4 new tires. But they are willing to work with us by giving us the tires at cost and doing a free balance but we would still have to pay for the alignment. Heck No. If they are willing to do that it says to me that they realize that it was their fault but they are going to do all they can to get around it. So I guess that I will take my business else where and get the tires done right. Sorry this is so long but I had to vent my frustrations of the whole situation. I tried to go to the gym tonight and I think that this was in the back of my mind just festering so I did not get in as good of a workout as I had anticipated. So again I say stupid Murdock Chevrolet. I guess that is what I get for buying a used car.
