I agree with everyone re: BMWs and especially my personal experience with our 2001 X5.....just did a quick trip to Vegas & back this past weekend on I-15 and can't believe how smooth, quiet, fun, and great handling our X5 (w/ sports pack) still is and we just broke 143K miles this past weekend....this is coming from someone who also has a E46 M3!
We were climbing up hills and passing all these cars and handling the curves on I-15 and unless I looked at the speedo, I had no idea I was going over 100 mph!
