Old Rovers or new? Since Leyland ceased existence ~20 years ago I'll assume old....I get to experience dissimilar metal corrosion (AL body) vs. plain old rust....
The newer ones are even worse, at least the old ones were simple, so you could fix them on the side of the road when they broke. The new models, larded up with every techno gizmo in existence, are likely going to require frequent towing to the dealership.
There's a reason why these companies have gone broke so many times, you know. When Lada can build a better Land Rover than Land Rover can, you're really in trouble.

Actually, up through the last ~250K miles in three new Rovers since 2011, the last time I had to have a DD towed was my ML320 in 2003. That vehicle was truly junk and, due to it and MB USA's response, I have never bought another MB nor do I plan to.
The new LR line, since ~2010 or so, is miles ahead of what they were in the period from the mid 90's until then. Have they been perfect? No, but no worse then the Jeeps or GM SUV I had before them....better then the Jeeps actually. Much as I liked them though, I would not go near one until they got better....knowing what I was buying and making an informed choice.
Just curious as to which ones you have experience with and what problems?
And in disclosure...I'm also amused by "junk" cars (just look at my sig)….
Being better than Chrysler is not a high bar to jump, especially after the Italian takeover.
