my 89 came cheap, at 1100 bucks, with very little rust and a nice interior, but the major problems when I got it were serious death wobble and a little engine knocking... well, and that almost all of the engine sensors needed replacement over the course of the first year.
in the 3 years I've owned it, it's become a 7000 dollar truck, with new stearing components, an old man emu lift, a set of all terrains, a new radiator, new hoses, new ccv parts when I broke them trying to clean them(brittle), new snsors from tps to cps to egr..., a second set of at's when the first set got slashed, an attempt at a rebuilt 4.0 that went bad after 6 months, a borla stainless header, an alpine deck, 3 new passenger swing out windows, for the three break ins, the last of which resulted in the loss of 6 quarts of oil..., a jasper 4.0 to replace the bad rebuld, and then a new egr and injector cleaning just to pass nystate emissions.... a week later, fuel pump catches fire on the freeway....
for 7-8 thousand dollars, I really wish I had a 96-99 with a shiney new paint job and 60k on the motor.... granted, I took some chances and had bad luck... and I like the old body style better... and it has character... but I don't know if an 89 is a good buy for a daily driver, unless you want a project.
