This is 10 or so years ago, back when Rover was almost always bringing up the bottom of the quality lists. I had a friend with one, more than once I passed her broken down on the side of the highway (we worked for the same company). She loved her RR though!I have a number of friends with Range Rovers. None have had significant mechanical issues. Now, there's electronic gremlins in the infotainment screen, which has been the problem for some time. But it's supposed to have been fixed with the current version. Time will tell though.
Expensive to repair? No more than any BMW or Mercedes or Audi really.
Now, if you have a diesel version... goooooooood luck. Thankfully, those aren't sold in the US. lol
