Yeah. As Linda said, aerokit is a dealer fit option. The original bumpers and skirts are, of course, yours. I've been offered them on the two previous occasions we've had aerokits fitted but declined to keep them.
I've seen some folks on MINI2 trying to sell them on in the past, with very limited success.
As for cluttering up the house? Personally I think they'd look really smart in the living room :clown:
