I am normally all for originality on Alfa Spiders but always wanted a Nardi steering wheel as well!Bought used from Japan of all places, has a couple of minor scuffs. The guy sent some origamis in the shape of birds in the box for my grand daughter. Very polite the Japanese.
I am not too strict with originality when it comes to cars of this nature, too many of them around, hence the non-standard interior.
I have the original steering wheel still if I ever wanted to go back to OEM.
Beautiful car you have!
