Welcome to the wonderful world of MINIs, I doubt any MINIac will mind if they catch you admiring or taking pictures of their beloved car.
I LOVE the coupe, it will be exciting to have one in the club to drool over. You might want to wax it well since we'll all be drooling over it.
I would say keep the 17" wheels, they look better for one thing. I'll let the motor geeks tell you all the other reasons. You also may want to ask about the All season tires, if you don't, they'll come with summer performance run flats that will not handle in the snow at all. I learned that lesson the hard, slipping and sliding way.
You want Xenon headlights because they are just that much better as far as being able to see at night. Another club member was telling me about getting a loaner that didn't have Xenon's and he really appreciated his xenon's when he got back in his own car.
The sport suspension will probably depend on how you're planning to drive. You'll want a stiffer suspension if you think you're going to want to have some fun on the turns.
I personally wouldn't want to live without my precious seat warmers either.
There is a lot you can do after market, as far as aesthetics. So things like vinyl can come later after you have bonded and know your cars personality.
Are you looking at the Lightening Blue?
Welcome to the club
