First time was on the test drive. We had been looking at 4 to 6 year old Jeeps for my son to drive, and were actually looking at an X3 at the dealer. I started it and it ran rough and smoked a lot - I know now it had the dreaded clogged CCV, or perhaps worse! Parked next to it was the X5, and the condition inside and out was outstanding for a car that was 8 years old. After a brief jaunt up and down the interstate, which did not, by the way, reveal how stiff the sport package suspension really is, we were asking ourselves why we were looking at noisy, rough, narly Jeeps where for the same coin we could buy a vehicle that was without a doubt in a different league.
