I have a 94 Range Rover with 98000 miles. Like orkrist said, little things do go wrong quite frequently. For an older model like mine, you can expect to spend around 2 grand a year in maintenance and repairs (if you go through the dealer for every little thing). However, if you are looking at a newer model, say a 99 or newer with bosch electronics and a decent warranty, they can be half way reliable. I've never heard anything bad in particular about rover transmissions (they're made by ZF) but I have heard of the occassional transfer case failure (mostly from owners who haven't ever shifted the thing into low range). If you plan to work on the vehicle yourself, an older model could be okay, just don't expect MB-like reliability. In regard to a CJ being as capable as a D90, it would have to be a pretty heavily modified CJ that could match a Defender in off road performance and sheer durability.
