What are the no-no's of car modifications?

I drove the proper "M5" the last time i sent my car in for service. I completely understand. That car was on the cusp of a super car. It flew, its entire personality changed completely in sport + mode and the suspension becomes hard and unforgiving as one would expect. It was wonderful car and experience. At 89k priced 25k less than what mine sold for at the time. I could have had that but needed to fit 4 adults.

So yes, i get that. My point remains, the M badge belongs on M cars, and my car, a 7 series Li car should NEVER be stamped with an M. There is no way they could ever make it an M. No amount of factory or aftermarket staple on part will do it. Its to heavy, and plush to bother with. (Alpina has a good try) And we all agree, the 7M or M7 or whatever you want to call should not or perhaps does not exist. However, it does, i have one, its fast as hell. in sport + it will rattle your teeth out and do donuts like a fool. It was this, the Alpina or an S63 Merc. I chose this because i needed it to be slightly reliable.

Let me finish with, I absolutely, without any compromise hate this car.
