M50 manifold swap is sort of a myth on m54s, the b30 manifold is very good and much better engineered, you get to keep disa too. To get max gains from m50 manifold you need to port match the head and even then I'm not sure it's worthwhile

@@LochyP there’s a dyno proven Thread on it. You lose a Little low end torque for high end gains. I suppose it depends on what Mike has in mind

Very vague question bud, it depends on what sort of drivers have owned it before and what servicing has been like. I’ve seen them in all sort of condition. If it’s been well looked after then it should be solid but you can only really take the previous owners word for it which isn’t gospel. Mine had done around 90,000 miles and I’ve put 30,000 miles on it getting kicked up and down country lanes most days and not a single thing has broken on it in the 4/5 years I’ve had it. But then I know of ones that break down almost weekly. It is pot luck, but that’s the same for any second hand car really. Maintenance is the key here. If you sense something going wrong fix it asap, otherwise you’ll get a domino affect with one problem causing several other problems.

It absolutely is pot luck. My 330ci spends more time off the road than on it, but that's because I can't afford to pay a mechanic so need to use the driveway when it's not raining

@@IMTHATELDER thanks dude, yea I mean it’s same principle with any car so long as you look after it (maintenance) then with a bit of luck shouldn’t be any issues. I think I’ll get it anyways as it’s one of my dream attainable cars so I wanna experience the car and ownership of such a legendary car :)
