I owned a 2000 Discovery for about 8 months and finally sold it at a HUGE loss due to reliability issues. In that 8 month period it was in the shop no less than 15 times (no kidding) for electrical issues, mechanical issues, etc. I bought it used but it was still under factory warranty (thank God!).
Go to
http://www.carpoint.com and read the owner reviews. All Land Rovers have issues. I have to admit the car was cool but come on! I have an employee with a 2002 Range Rover. He also has the same issues and get's a loaner once a month.
Also, a 30K service ran me $1,300.00! The 30K service on our first H2 ran only $750 at the dealership even!
Land Rovers will also get you when you go to sell them. They are like Jaguars when it comes to resale.
