Would I be pretty dumb to get the wheel without getting harnesses too? lol.
Depends whether your planning on having a big accident in your car or not?
Seriously though, I drove an 850cc mini when I passed my test for a few months then upgraded to a 1000cc mini
then a 205 gti. None of these had an air bag or any real safety features. I never felt dumb driving these cars.
I think at the end of the day you either decide to take the risk or not. Changing the steering wheel would make an amazing difference to how your 182 feels to drive but it would also be less safe in an accident.
You cant fit a harness to a standard seat.
