Car has had no problems other than the removable roof panel that GM replaced at no charge. The car gets abour 23 mpg in the city and 31 mpg on the freeway with comfort, power, and style. It has handled the dust and heat of the Arizona summers (the A?C works very quickly even in 110 degrees). Great daily driver.
The powerful engine, great gas mileage
Replace the stock Goodyear tires with a better quailty tire like Michelin.
