Oh yeah no very different problems in both. W10/11 both suffer with overheating which by extension means head gaskets. The whole cooling system is an issue primarily on a r53 due to the supercharger, and if you have a Midlands (2001-2004 r50’s)/cvt gearbox you chew threw clutches, howevef the getrag is a resilient clutch in the cooper s (2001-2006 and the r50 2005-2006) it doesn’t have any major issues compared to the r56 after that, but suffers from age related niggles.
That, and I doubt they’ve gone around modding
