2005 Buick LaCrosse CXS 4dr Sedan (3.6L 6cyl 4A)


I've had my Lacrosse for about six months now. It is quieter than my 99 Regal was and the ride is smoother. The interior comfort is about the same. My major complaint is gas mileage. It is getting 19.6 average for combined city and highway driving (about 50/50). My 99 Regal with the SC3800 engine got 22-23 mpg. Same driver, same route, different car. I've seen comments about the performance of the 3.6L engine in the CXS, but my experience is performance is nothing to get excited about. It's better than the 3.8L, but a long way from my 99 Regal GSE.

Best Features

I like the memory seat and remote start. The programmability of the key fob features is nice. I also like the driver seat adjustable lumbar support.

Worst Features

Peformance and fuel economy of the CXS is unacceptable! I could live with the performance if the fuel economy was better. I expected it to be.
