I bought a brand new 2001 Blazer ZR2 and kept it for almost 10 years. As much as I loved the look of the vehicle, it was a build quality and maint nightmare. New ball joints at 35,000 miles, steering wheel pump failure, several electrical system issues, shimmys and shakes as things loosened up... I swore I'd never own another Chevy truck as a result.
Now, 6 years later, I just ordered a new Colorado. I think (hope?) they are built better than they were 15 years ago. I was back and forth on the ZR2 vs Z71, and chose the Z71 diesel. This ZR2 just doesn't 'pop' like the old ZR2's did. Tough call, though.
Looking forward to seeing these things on the road, even if I'm not driving one.
