This car is a super car


The cars has only had a dead battery.

General Comments:

This car is like a 4 door version of the Trans Am. This car does 0-60 in 6.0 seconds. It's the fastest and most fuel efficient car we've owned. The car has the best top speed as well. It tops out at 130 M.P.H.

My air conditoner is not getting cold. The low coolant light is coming on. But when I bought it the air conditioner was working just fine.

The car rides very low, I was wondering if it needed shocks or springs.

General Comments:

This is a very nice car for what it cost.

It is true, the plastic plenum on the 3.8 Bonneville is expensive. And will not give a warning. The EGR valve malfunctioned on my car and this is what melted the plastic. Too bad that GM did not understand what the customer wanted. Placing plastic on top of a hot motor, not a good idea. Maybe this is the reason the big three are losing market share to the imports. It is a a really nice car, not sure if the next one will be a GM though.
