For a truck, not really. My old truck was a 2007 and I bought it in 2010 with 66000 miles on it. It was just this past year that I hit 150,000 miles. I don't really feel like the engine started running right until it hit 100k. That is of course until the cylinder started misfiring. It isn't a diesel engine. It would have been my preferred choice, but the cost of entry is much higher even for a used diesel. Plus people don't tend to get rid of them once they have them so the market is relatively small.
