I'm looking at getting a Silverado 1500 with the 5.3. I'm down to a few trucks in the area, but my question is if there is any significant differences between the 2000-2002? If there is no significants differences I'm going with the better deal, but if there is, then I'll probably go with the 2002 even though I like the 2001 and 2000 I'm looking at better.
