I haven't seen many comments on this subject on the M3W forum.
I have recently fitted a Moto-Lita wheel.
http://tinypic.com/r/29pdb1c/8 I think that it goes very well with the tan upholstery.
The standard wheel is definitely not the car's best feature, it's pretty clunky and seems to be designed to obscure the rev counter to maximum effect! The thinner rim and flattened top spokes of the M-L wheel help here a lot. Some say it doesn't feel as comfortable to the hands as the standard wheel, but hands up all those who bought a M3W for its comfort!
