I bought mine 2 weeks ago. 7800 miles. Termi exhausts, full Ducati service and 2 owners. £8150. It was up for £8828, but got the dealer down to that for a straight cash deal. I had a look at a few 899's and they were all about 8500-9000 mark. All with roughly the same mileage, condition varied a little.
I wondered if you were the chap with the broken leg buying the 899 the other day in Lincoln? Really nice bike and caught my eye... 899's are on the up and up.
