Rovers suffer from an excess of personality.
You either like that in a vehicle, which makes you a contender for ownership, or you don't, which means you should consider a vehicle built in Japan -- where they seem to excel at building vehicles without personality.
Generally, I think Rovers are stout hearted beasts whose reliability in major components is at least comparable to other major manufacturers. I think, actually, better.
But I would not recommend them to any one who doesn't currently change their own oil and does at least occasional work on their own cars.
The reason is Rovers require a little more TLC than your average car. Plan on spending one Sunday morning a month (at least) topping off all the fluids. My D1 transfer case has leaked oil for the last 75,000 miles. Works great. Just needs a squirt now and again. The steering box on our RRC reliably drinks a gallon of ATF a year, and has for years. Rovers mark their territory: your garage and driveway will soon be covered a quilt work of oil stains.
The other reason you need to be a little handy is that it is the little things that drives some people out of Rover ownership. I've found that the major components -- engine, tranny, etc. are reliable and built well. The little things -- maybe not so much. For example, on my D1 I think I have replaced the window switches about nine times. There are only four switches. So each one has been replaced at least twice.
Each time, this set me back about 20 bucks for the switches and about five minutes for the time. Now, if I had to take it to the mechanic each time at $100 a trip, I'd have a thousand dollars invested in window switches and I would be unhappy.
Rovers have a multitude of issues like this, I've removed one door panel to fix a sticky and/or broken latch mechanism on one door about ten times. There is not a door on the vehicle that I have not had the panel off at one point or another.
Rovers are extremely quirky. I hit a bump once while carrying my inlaws from the airport and it turned the headlights off and the flashers on -- which didn't fix itself until I pulled over, turned the rig off and started it up again. Never had that problem again. Our RRC, about once a year, has the tachometer go completely haywire for about twenty minutes. Then it is fine for another year.
Any Rover owner will have dozens of stories like this. I've only had the D1 not start on me once -- but I've had the doors refuse to open about a thousand times (for various reasons).
I think most people visiting Discoweb do not consider such issues to be a burden, and maybe even find it an enjoyable (or at least amusing) part of ownership. But I had a mechanically inept friend who asked about buying a RRC advertised in our neighborhood and I told him that I thought he would not be able to afford to fix the little things that invariably would go wrong because he was not the type to get his hands dirty.
The Rovers are great vehicles in inclement weather and under adverse conditions. But if you are just expecting to walk up to the vehicle, turn the key and drive away -- each and every time -- well, you might be disappointed.
A final thought.
I tell people, "If you view the Rover as a hobby, you will be very happy. If you view it purely as transportation, you are probably destined to be disappointed."
Hope this helps (and maybe we'll see you out there!)
