Don't get me wrong I love Rovers, always been a big fan - particularly 600's - very nearly bought a late 1.8 one before I had the 25.
It was only 6 years old, in nice nick, with a pretty good service history. But it had electrical issues all the way through owning it - so much so I had to purchase some sykes pickavant diagnostic gear for it, which kinda got me into that buts thats another story! - in the 15 months we owned it had;
Both CV Gaitors
Problems with sticking front brake calipers
New MAF
Front wiring loom issues which meant it went into 'Limp Home' mode everytime it rained
2 new clutch cables
Rear wiring loom issues meaning all the rear lights failed.
Oil cooler pipes that rusted/split putting oil all over the inner wing/brakes/tyre.
Air con failed due to a fractured pipe.
Too many other small jobs to mention.
What was surprising was the -relatively - poor quality of wiring/connectors and the fixings were regularly seized when you tried to remove them. The car was originally from newcastle - this may have had something to do with that i.e. coastal location/from further up north?
It was a lovely quick - 2 litre turbo diesel - economical, nice looking thing and very nice handling. But, if I didn't do a lot of my own work it would have cost a fortune - it was expensive even for the parts - I was under it every other weekend and in the end just couldn't trust it as my missus used it mostly.
I've still got a soft spot for Rovers and I would love a 75 - would I own another - probably not at this point.
Where as all the Vauxhalls I've owned whilst not quite as fancy, and perhaps a bit more understated, have always been - relatively - trouble free. Truth be told I'm a Vauxhall fan anyway and getting a GM campervan was a big bonus

The quality / simplicity of the rascals certainly seems to be a strong point anyway.
