I've owned 7 Land Rovers (still have three right now) and they've varied on the issues they had.
I have a '95 Range Rover (original body style) that has 140K miles and it had no warranty claims in the first 50K miles and since then I've done about $1K in work on it outside of regular maintenance. This one I will never give up.
My '97 Defender 90 never had a single issue...but then again...it's the most spartan LR imported to NA since '87.
My '92 Range Rover just blew up a rear diff...completely unexpected and on my street at 69K miles. Outside of this it is like the '95 with nothing other than regular scheduled maintenance...another I won't part with.
My '99 Discovery was a POS. It was the first year of a new model...and it showed. I got rid of it as fast as possible.
My '01 Discovery I had until 95K. It had the Active Cornering Enhancement hydrolic sway bar system. I had many warranty claims with this system and decided I wanted out of the truck before the 100K warranty expired. Other than that no serious problems.
My '00 Range Rover has had absolutely no problems other than broken winshield washer jets until lately. At 98K miles I have about $3000 worth of problems and it is in the garage until I decide to start working on it.
The last one was a '73 model and I never finished it. I ended up scraping it for parts.
My 100 is an '02 with 85K miles and everything looks great so far. I think once I finish the repairs on my '00 Range Rover I will consider selling it and replacing it with either a newer LX470 (like '04 or '05), a '04 or '05 Range Rover (with lots of warranty) or say screw it...get to join a new club...and buy a 100 LC and start setting it up to use off road so I can use the '92 with the LR club and the 100 with the LC club - right now I like this option best
