Depending on what model you want i'd keep looking
so long as your in no rush.....I spent about 6 weeks watching the adds on auto trader and the MCN before buying mine.
I was'nt worried about having a top model and settled for a 748E.
Two previous owners, registered September 2003 - 53 plate, full Ducati service history, just under 6000m, carbon hugger and front fender, Termi's, and i haggled him three hundred as it was due a set of belts - £4300
Granted it was'nt on my door step, i had to travel to Lewes near Brighton to pick it up which was about a 330m round trip, but was worth waiting and traveling for
Its also worth keeping an eye on the site, there's allways a bargin to be had here
