Hi guys I was wondering if an original modification from the famous Zanasi garage will affect the value of a Ferrari. I was wondering to change the kind and the colour of the leather of the steering wheel of my 812 . Is this kind of modification intended as a “ genuine Ferrari “ part ? I know that many people use to modify their Ferraris with Zanasi garage and from what I know they are the company that do all the tailor made modification for ferrari cars ( but maybe I am wrong ). Thank u!
