If your able to sell off any parts, let us know...
and if u havent told the insurance company about the change or mags/tyres... you might not then be convered under insurance as i'm sure you have to tell them about all changes made to the car.
that i'm not 100% sure but best to check up on that.
Some people have told me you have to, some said some things aren't compulsory to tell insurance companies such as headdecks, etc etc.
