Bought it new. Yes the steering shaft went twice-but I wrote to GM and they paid for out of warranty ($223)repair. Original tires noisy, replaced with Regatta's. The 3800 engine is a dream, quick and 28 mpg at 75 mph. The ABS/traction control feature is absolutely great for snow. The car is still tight and handles extreamly well after five years. I just saw the 2006 Impala at a car show and can't wait to buy it. (and keep this one too). Unlike the smaller sedans this one is built tight and well and is without the excessive road noise you get in the earlier models. Lastly the brakes were imporoved over previous Lumina's although you warp rotors prior to pad replacement, but you do stop.
The heated leather seats, I thought it was an unnecessary option. I love them in the winter.
Larger diameter cup holder. Rear seat cup holders also.
