Well, I finally had it with my Chevy dealer. I bought a 2005/ 4500 duramaxAllison, new in 2005. We put 14800 miles on it and I was happy, but had been thinking about tradeing it for a 4x4 4500, UNTIL! I had a warranty issue. A tranny line started to leak, my dealer didnt want to work on the truck. He wanted me to take it to another dealer about 75 miles away. It took a quite a bit of argueing to get the problem fixed, but they finally ordered the line and installed it. Had the truck back for a week and my guys said it was still leaking fluid. I went to check it out and it was an axle seal, called dealer and they refused to work on it, again! I have bought 7 new vehicles from this dealer, but enough is enough, I am now the proud owner of a 2008 F450 4x4 Super Duty Ford. Its in the shop having a bed put on it and I should have it back by this weekend. I plan on driving it onto the chevy lot and letting the manager take a look at what he could have sold me if he hadnt of been a total asswipe.
