The worst thing I ever did was buy a beautifully kept up Blazer for a move across country. After over $1,000 in repairs before I got out of town (brakes, brakes, new radiator, brakes again.. egr shmee-g-r, oil change, etc) and another $350 on the road, in the middle of nowhere, for a new fuel pump, the thing lasted only 5 months thru the winter (without 4WD, which wouldnt work) before the engine blew. This car was very well taken care of by the previous owner and myself. Who knew? I knew there was a reason my Dad made that face when I said I was buying a Chevy. I guess after the Citation in the '80's he knew what was up.
This is a nice-looking, comfortable vehicle which, when it runs well, is great to drive.
They only made that engine for one year, so that's fixed, but brakes and the push button 4WD. I have also heard that the tranny goes bad quick. Mine was close.
