My tailpipe rusted off 3 years after I bought it & found that you could not just replace the tailpipe; you need a 'complete' exhaust system. The price of the system $18,000 (not including labor). At 5 1/2 years, my front "Crossmember Stablizer" RUSTED off (with NO WARNING); it cost $350.00 for the part and another $200 in labor.GM would do NOTHING because it was over 80,000 miles. WHAT MILEAGE HAS TO DO WITH A "RUSTING FRAME" THEY COULD NOT EXPLAIN? Anyway, I'm happy with the vechicle over all, but watch for rust underneath. it is 'very light' metal.

Better electrical system. Heavier sheet metal on frame, Better quality door handles especially the rear cargo door!
