Admittedly one of the most refined and capable luxury SUVs made...when it's not in the shop. Most common trouble spot is the air suspension system, which will leave you stranded when it fails. The complex electrical system is British...not high in the reliability category. Don't expect much warmth from the heated seats, if they're even working. They're prone to early failure. Make sure that you do not own this vehicle without a warranty as the average trip to the shop is in excess of $1,000, not including a rental car and flatbed.
Very capable in the snow and ice. This vehicle will go through absolutely anything! I've personally forded 18" of water with no problem, although I'm sure it will do more.
The 2000 model year and later have improved upon most of the trouble spots and are much more reliable.
