Without actually inspecting it in person and purely based on the specs and pictures this is an awesome buy at that price. I just paid about double that for an 03 with 91k miles and felt good about the price.
1) Sliding door (will not clear wider tires).
2) Regular, not extended body (opinions on that are split, it's a trade-off).
3) miles on chassis, but at that price, you can afford to replace some things.
That's a decent price, but not also that unusual for a well used 2wd van.
