I brought my Range Rover here when my "inactive suspension" sign came on. When I first took it there, they inspected it and got it recalibrated. But as soon as I left, it failed again. Needless to say I had doubts about their ability and knowledge. I called immediately (after 6pm) and got the dealer manager. He then contacted the service manager. I received a call back right away and brought my car back the next morning. To make a long story short, I had to replace the air compressor and struts at a whopping $6000 and that was with some help from them. Overall, the service manager and staff was very attentive and always let me know what was going on... They had my car off and on for about a month.
