Morning Andy
Welcome to the Forum
The M cars will always have a harsher ride but apart from that it's the Grunt that is addictive.
I have owned performance/tuned cars since the 1960's, current 2 x X5. My daily drive an E70 Diesel with 280+ hp and my E53 4.6is with Dinan upgrades 400+ hp. My wife's car is a Subaru Outback with a Perrin engine 400+ hp. This year see's my big 80 so I guess we are proof that getting older doesn't mean you have to grow up 🤣
I hope you find what your looking for
