wouldn't do it. not a great price, lot of miles, even though the injectors have been replaced they seem to have a habit of going out again on that year model. Don't know why, theoretically they should be just as good as the current one's, but they don't seem to be.

X2 Scott. Pass on this one.

If it was well cared for and not hammered on I'd say its a decent deal considering the price of Duramax trucks these days, power differences from the 04 to the 06 are minimal, if you want a little more there are tons of programmers and tuning software out there, an 04 could either be LB7 or LLY either are good options, LB7's had injetor issues but with 244 on it om sure if its an LB7 they have been done. LLY's have a few issues with cooling but can all be fixed with minor cheap mods. That truck with lower mileage say, 150k range would bring almost 20k around here.
