2006-2009 Range Rover MkIII / L322
Like anything a lot depends on how it was treated through its life, was it maintained properly, was it beat on, etc. That said need to know which generation you're looking at, the BMW 2002 to 2005, the Jaguar/Ford 2006 to 2010, or later. All of them are subject to air suspension issues, but 95% of the time, that's just a wear and tear item with the air bladders just wearing out and causing the truck to lower to the bump stops. Guessing on the somewhat cheap statement I'm going to guess its a BMW version, or at best an 06 model. Need to know what you're looking at.
