Before I bought my NEW Dmax, I was looking at used ones. I ran across a dealer that had an 02 for a good deal about a yr ago. It was priced right and low miles (5200). When I went to see it, the first thing I noticed was new tires. I thought that was kinda odd, but Like most Dmax owners, the first thing they do is put Bigger tires on to make it look better. Then I got inside. The Leather seat were very much "Broken in". After talking to the dealer, it was a Truck from Canada. He says they have a connection on getting trucks from there all the time. He tried to tell me that people buy them, put a few miles on them and get another one. But why would so many people in Canada spend that much money for a diesel truck to drive 5000 miles and take a hugh hit on trading it in for a new one? After doing some research, I guess it is a big thing going on swapping vehicles between US and Canada. They have to convert miles over, and it is hard to police it. There has been some big Stings that have caught some, but alot get away. Being in the Detroit area, I know a few GM engineers that can hook up a laptop and "correct" every computer that holds the mileage, well so they say. I know plenty of people that have done it and never got caught. Even friends that work at dealers tell me what they "do". Personally, I don't think it is worth the risk with a diesel engine. They seem to hold their value pretty fair. As for a gasser..........
