Anyone know any companies that wil do this using genuine BMW parts? (not some naff 3rd party unit)

 

I know BMW will want £2500+, don't know of any TP outfits.

There is a bit less room to work with on M3's due to additional cross bracing etc. behind the glovebox and dash so that may push the price up.

Maybe find a wrecked one and rip all the stuff out to save on parts and get it fitted by an expert?

Cheers,

Phil
