OK, I couldn't decide on just one "must have" because I wouldn't have my MINI without any of these.

Must have list;
Cooper S - too much fun not to have
Manual tranny - glad to have a wife that also likes to shift for herself
LSD - great for winter and sporty motoring, if the factory won't offer, it will have to be aftermarket
Light-In-Sight.com - tired of a stiff neck trying to see the traffic lights
16" wheels - lighter, better ride, better performance
Cloth seats - warmer in the winter, cooler in the summer, not as slippery
Heated seats - you won't understand if you have to ask
Xenons - great distribution pattern, very bright
rear fogs - can't stand blank switch locations
Multi-function steering wheel - cruise control and stereo controls right at hand


Must avoid list;
Sun roof - too hot, too heavy, too noisy
