Was at Concorso Italino over the weekend. Saw several. Looks like the owner of a local karting place has one (also owns a Elise). You could try shooting him a email via
info@lemanskarting.com.
You could also try the Fiat America Club (NorCA based)-
FIAT America
One of the Fiat guys that autox with us also sells Fiat parts and cars (had a booth at Concorso). I'll dig up his contact info and PM you, with it.
