I went from a ZR2 Blazer to a Cobalt. I miss the 4WD, but love the fuel economy. I drive approx. 3000mi. per month and have saved a lot in gas $$. But at 18000mi the trans. control module fried, I had to have a whole new sunroof put in within 2 weeks of purchase, the rearview mirror fell off, the e-brake light randomly comes on & i never use the e-brake, the cd player has a mond of its own. When braking hard on the highway, it makes a loud rubbing noise that nobody can figure out. But for the gas $$ I save these are just little things that are under warranty. Can't wait to see what goes wrong once the warranty runs out.
