I think I found a pretty nice diesel blazer, its still 24v(yuck), as it was a military blazer before hand. Anyways, got a few general questions.. its got 44,xxx stock miles thus far, but the guy rebuilt the tranny. Anyone know why he might do that?? Just wanna get your points of view before I ask him, so I can attempt to detect any BS. Its got 4.56 gears in it, 35 new lifted tires, and hes selling it cause he needs the room and such. Anyways, as far as the story.. how plausible is it sounding? Its only 3500$, so i'm a bit skeptic. Also! Is it just dumb to go buy a 20mpg(ish) diesel truck with the fuel prices the way they are? I have no honest to god need for a giant honking blazer, except for the occasional dirt bike trip, and off-roading. Sad to admit this.. but at 20mpg, its 9mpg better then my S-10 right now. I'm sure I could get that 20mpg up to 25ish if I swap in lower gears(say 3.51's or whatever they are ), but still. I'm looking more towards the fact that should fuel become a crazy issue in a year or two, I can rebuild the engine into a bio diesel motor.. and just go on that. Just hoping for a guiding light here... THanks P.S. its an 85 K5 Blazer, 6.2l Diesel, 4.56's gears with a "Rebuilt transmission and Allison convertor", 44,xxx miles on it. No A/C, and the artic heater stuff was removed but he kept oil pan and tranny pan from it. Body is in good shape, he says power train is also.
