Drove the Blazer for one-year and sold it thinking to upgrade, but probably let it go too cheap. The 4.3 V6 was a powerful engine, the LT trim was awesome, but I ran into drivetrain problems and it began to leak out of the rear main seal at around 115k, then it started leaking anti-freeze from the head gaskets. Also had to replace a leaky CV axle, then just started leaking again from the front differential. Also a vacuum line disconnected and the electronic 4x4 wouldn't engage. The AC had some problems too. Overall this was a good car, but with over 100k I wasn't ready to accept the maintenance costs and got sick of leaking fluids.
Trim: Sunroof, power accessories; Powerful for a V6.
