I had to go to Dallas, Texas, usa, on business recently and rented a 2004 Impala from the nearby Budget rent-a-vehicle. It had a 3400cc engine and power everything. Beginning odo= 26 miles. Ending odo= 1027 miles.
On the good side, the driver's seat was pretty nice with the power bolsters. The radio/cd was acceptable. It rode with minimal road noise and handling was quite good. The trunk is large and can easily hold 2 suitcases and several tool boxes (about 200 lbs total).
On the bad side, I found it to be very underpowered and uncomfortable on long trips. Accelerating into traffic or just maintaining speed while going up hills caused the trans to frequently downshift into second gear. As much as the engine and trans labored on that trip I seriously doubt that they will make 100,000 miles.
I could not comfortably hold the steering wheel at the 9 position (or the 3 position) due to the large center spoke.
As usual with recent GM products, the door sills are about 4 inches too high and made it impossible to lay my arm on the open window sill.
Also, as usual with recent GM products, there is no padding on either the center or door arm rests.
The inside rear view mirror is much to small and way too dark. The limited rear view took some getting used to.
Would I buy one? No. My old 1992 Grand Am 3300 is a much better car. It was designed better, is more comfortable, and has more power.
