Bought the vehicle 4 years old and kept it until 2008. Our 2nd RR. Probably better experience then most on a RR. This car has been vary reliable. Not typically the case from what I read. Key is to find a reliable NON DEALERSHIP mechanic. Remember it's a Range Rover, not a Toyota.
Drives like a car. Solid, safe vehicle. Looks great and has a timeless design.
At the first sign of trouble replace air suspension with coil. It will be the best $1200 you spend! Replaced waterpump twice, head gasket once.
