Pimpy

Put an old Momo in the car. A bit sacrilegious in a Mercedes, but this is about feel not looks. I'll probably replace it later with an all-black Momo Competition, but this should give the car a little sportier feel and a little more space in the cabin. That stock wheel just felt like it was meant for a boat not a car.
Later I'll pull the airbag warning light. I always use my seatbelt, so I don't have much use for an airbag anyway.

Cost:

• Momo Hub: $75
• Momo Race Wheel: free, already had it lying around
