The most miles I ever put on any motor was about 230k on the E36 323i coupe M52TUB25 motor that I kept in The Netherlands from around 2001.
That car was epic.
It took me to Germany, Poland, Czech Republic, Portugal, Spain, France on business on a regular basis and as it was a UK registered car back to the UK every year for MOT's, all without missing a beat! Cruising through Germany at a constant, steady 100mph was effortless and comfortable and with the fold-down rear seats I could load it up with a shedload of whatever.
I bought it with about 30k miles on the clock in '99 from a BMW re-seller who didn't realise that it had had a short engine replacement at around 11k miles and was a surprise to me when I found out. For 10k cash it was also a pretty good deal considering someone had paid the thick end of 35k for it originally.
It was on the original clutch, manual gearbox, diff and even exhaust system until some twod t-boned me in Amsterdam back in 2016 when it was showing 261k miles.
To be honest I'd thought about getting shut of it way before then as corrosion had started to creep in around the front and rear arches as well as the leading edge of the bonnet, so it was looking a bit scruffy externally. By then it was also suffering from a bit of an identity crisis as E36 Coupes were perceived as a bit chavvy at best and I used to get tailgated and cut up by tw@ts on a regular basis in NL. But everything still worked and functioned as new; the aircon, sunroof, all the lekky bits n bobs worked and the economy on long runs was also outstanding. I was genuinely quite sad when it got carted off by someone who actually decided to pay me real money with the intention of straightening and converting into a drift monster.
So I have every confidence that the M54B30 engine in my zed is going to see at least another 150k miles if looked after properly and unless some twonk in a Twingo tapping away on Tinder while tootling through traffic doesn't tw@t into me!
