I got a call from my insurance company last Tuesday, asking S/N for my 355. Told them my car is in the shop for repair, but should be back this week, at that time. Well, the car is not repaired yet, but the insurance company called again today. The problem is that S/N I reported indicates it is not Ferrari, but '99 Fiat according to insurance database. They suspected I or the seller is doing something unordinary, especially changing spider to coupe in less than 2 months. They want to look at my car!! Does anyone experience somthing like this?? If so, what could be happening here? Should I be concerned?
