Advanced Motor Sports in Dallas Texas currently has three 1974 Ducati 750SSs in their motorcycle dealership. These are the ones with duck Green frames and silver tank, seat, and fairing. Two have been restored and one is all original. These bikes are going for near 100K at auction and I'll bet the original bike will go for more even if there are a few scratches and some fading paint.
