Unless one gets extra credit for high mileage (I am at 109K on my 1999 540i/6), then I would have to nominate Matt's highly sweet ride over mine already. My car is totally stock, whereas he's already done the headlights and taillights, which are still lingering on my "to-do" list (along with window tint). I've been too busy taking care of 100K mile and Inspection II maintenance (but all is done now)...
