I do not have an aftermarket steering wheel, or seats, but I do want them in the future.
Right now, I ONLY drive the car on the street, but if it were not for the insurance companies either; denying any medical claims at all without airbags, or charging me insane rates if I tell them I don't have them up front, or them denying me any coverage whatsoever without airbags, I would already have an aftermarket wheel in the car, and I would take my chances on the 'safety' aspect (I ALWAYS wear the factory seat belts).
I do not care one bit about the OEM steering wheel buttons since I NEVER use cruise control (haven't used it even
once since buying the car 4 years ago!), and I don't use the sound system controls there either.
The same goes for aftermarket seats, which I REALLY want since I cannot stand the Recaros (why I
specifically ordered the car without them!), and don't mind the base seats, except I do want something which holds me in place better than those do (and yeah, I
will admit it, for the 'look' as well
).
