As the owner of a 2002 Freelander which I traded in for a 2003 Discovery I can tell everyone to take seriously the ratings given by both JD Power & Associates and Consumer Reports magazine (among others).  JD Power & Associates reviewed 38 auto manufacturers and Land Rover placed right at the bottom for the reliability of all their vehicles.  Consumer Reports magazine ranks Land Rover vehicles as "much worse than average" for reliability but also displays in graph form how much worse than average Land Rover vehicles actually are.  When compared among 48 other midsize SUV's, the Range Rover, LR3 and Range Rover Sport all ranked between -129% to -195% in reliability (a score of zero is perfectly average reliability, with 22 other mid size SUV's scoring above average).  Again Land Rover is dead last for reliability.  For the premium price paid for these vehicles you can expect Land Rover to only issue recalls when forced to do so by the government and you will spend lots of time, hassle and money on frequent repairs.  Be warned! Look very carefully at the data out there in the press, Land Rovers are expensive pieces of junk.  

Owners of 2003 Discovery vehicles should check out the Land Rover issued "Technical Alert" at the following link: http://home.comcast.net/~bhcmbailey/lrna_tsb.pdf
There is a class action lawsuit being prepared by a lawyer named Michael Wing for 2003 Discovery owners whose VIN ranges appear in the Technical Alert.  The contact information for Mr. Wing's lawfirm can be found at  http://www.michaelwing.com  

No offense, but I've never held Rovers in a high regard in terms of reliability. I don't have anything against LR3 or Discovery drivers, but RR drivers are generally arrogant tools on the road.
