With any make or model of car regular servicing is key. I had a 360GLT cover 270,000 miles without any issues and a 2.0lt V40 370,000 miles again without any issues. In both cases the body rotted before the mechanics gave up. I do all my own servicing and am fastidious in approach and don't skimp.
We bought a 2007 Mini Cooper for 'er indoors with 40,000 miles on the clock several years ago. It is now on 107,000 miles and still going strong. It is the non turbo N12 engine and if you read online reports you would never touch one. Timing chains collapse at 50,000, cats give up at 70,000 - if you are lucky, sooner if not. Oil leaks are impossible to cure, pistons implode etc, etc, and it goes on and on. With these engines it is important to keep the oil level topped up as they do like a drop to drink. Service interval is 18,000 miles and as a lot of them are driven by young women, never get the oil checked between services - I suspect many are run practically dry.
I changed the timing chain at 100,000 miles - not because it needed it, but just in case. The cat did give up at 102,000 miles and it did develop a couple of oil leaks which £37 worth of new gaskets and a day of my labour completely cured. Apart from the above and regular service items it has been a remarkable little car and one we both love.
The heater fan did become noisy at around 70,000 miles - a common issue, but a new fan cured that. Only down side was the dash had to be completely dismantled to fit. The dash doesn't come out in one piece, but every single item has to be dismantled in a set sequence. That was three days work for me as it was the first time and I didn't want to break any tabs etc. Attachments show the extent of the stripping and finished job. No tabs were injured during the fitting process
