I have had my Monte Carlo for almost two years. Pretty good overall car. It's very reliable and I haven't had too many problems with it. However, the gas mileage is terrible in the city, I average about 18 mpg, much better on the road though. The hinge on the glove compartment broke, and braking in the rain was bad until I had the front fender liners trimmed. Overall I have been happy with the performance, never lost a race with any high-schoolers at stop lights with their Civics and Eclipses!
Definitely power! Wish they offered the car in a manual though, it would be more fun.
Add a manual transmission. Make the turning radius better! (hard to park in tight spaces) Better quality of interior and better gas mileage!
