I'm picking up my
MCS from the dealership today and it is my first mini

! I've taken a step sideways and have traded in my BMW M3 Evo Convertible, halving the horsepower and engine capacity at the same time

At some point I'll be looking to modify the engine to gain a few mores horses, plus if I decide to keep the car long term I will be modifying the suspension, brakes and style of the car.
My current TLC runs out next week and I'm looking at buying the TLC XL package. I presume that you are limited with regards to what modifications you can carry out before the dealership refuses to service it and the agreement is invalidated. I've read some previous articles in magazines and on the net, each giving different stories with regards to what you can and can't get away with?
Just wanted to hear from everybodies personal experience with this?
