Kaz,
I was not a big fan of Chrysler products to begin with but my wife and I purchased a 2007 Nitro brand new. It was pretty good at first except for the usual cheap and poorly engineered interior. Visable seams in the dash board and overall poor quality. Soon we started hearing a noise and finally isolated it to the roof rack. Now both are pulling up on the front and it is over mileage by a few thousand miles.
I tried to change the brakes today and was unable to get it done. I have changed pads on my Land Rover, my wife's old BMW, Fords, Chevy's, and have had no problems. I am so disappointed with Chrysler's workmanship I vow to never by another one of their products again. In fact two people within the last week asked me about the Nitro and I told them to find another car and another car company.
Good Luck.
