Bought the 2003 new, previously owned a new 2000. The 2000 my below average, but the 2003 is a really crummy car. 21mpg, too low, Horrendous road noise that the dealer couldn't fix. can't keep tires on it, 2 sets in 55k. No torque in drive without hitting passing gear. I had the extended warr, but have had constant problems, motor mounts caused the engine to strike the firewall, rotors were out of balance, replaced myself, check engine light problem, the dealer kept it 2 days, and finally said a squirrel had chewed a wire. If you believe that I have a bridge I want to sell you. Last problem was traction light came on, and dealer wanted $1200 to fix, but finally after many meeting, fixed it.
The V6, is pretty good in acceleration, except it has no torque, in drive without downshifting.
Send their design and manufacturing team to school at Toyota or BMW. This is a dog of a car. I have owned my last Chevy.
