2005 Chevrolet Blazer LS 4WD 2dr SUV (4.3L 6cyl 5M)
I have owned my ZR2 Blazer for 21 months. It is a comfortable vehicle in the city and in the country. It is ablsolutely terrible on the highway. It has no tolerance to a gusty cross wind. It goes all over the road. I believe the problem to be the tires. I am getting the published fuel mileage however it doesn't come close to my '89 S-10 which also had a 4.3. I would think the Vortec 4.3 should get better mileage than a throttle body 4.3.
Looks. It is a sharp looking vehicle and great in town especially in winter and on ice.The auto-trac transfer case is the answer. Its an easy vehicle to park as it has a very short turning radius.
