well thanks for the info , i know blazers have there engine problems and also tranny problems, ive heard engines going at 88k lol, and trannys at 100k , its just to bad because i like the chevy blazers, but dont want to have to replace motors or trannys all the time lol. well my bro just bought a Grand cherokee 156k paid $4500 i think a little over priced but i love it, lots of room i love the straigh six motor , u actually can change the plugs and wires yourself.
