Wonderful vehicle there is a reason they discontinued the 4.3 Liter CPI engine. Certain things go out like clockwork but the truck is almost 20 years old now. The thing had over 300k on the engine when some crazy woman ran the truck over while I at a stop in traffic. It folded the bed under the cab area and the frame was bent near double. I walked away from the wreck with a concussion.
I love my Sonoma! I would say that the ONLY thing wrong with it is that it isn't the most comfortable truck to be in on long trips. But the power in the 4.3 is amazing! I've only got 95,000 miles on mine and I've never had any problems with it whatsoever. I highly recommend the Sonoma if you're thinking about buying a little truck, it looks little, but it's got the power of a full-size.
Well first off the truck is a overall good truck, but the performance stinks. I definatelly recommend the best top of the line tires for traction. The brake system in it is awful, and it will skid or turn sideways very easily. How this truck hasn't caused more rear end collisions is a miracle, and but by God I think it would have. The brakes lock up and it takes forever to get this thing to stop, have been told was a problem with the anti lock braking system in them back them. I suggest you use pleny of room for stopping when driving especially if the road is wet at all, and be very careful, and never ever drive on snow, or else you got really good insurance.
The first year of the new body style, I fianlly traded mine in on the last year or the same body style (2003). My 1994 GMC Sonoma 4x4 had 211,000 miles on it at the time. Only major repair was a new alternator at 160,000miles. Blue Book on these is very underrated.
