I bought my K5 1000 from the Donington Superbike Factory 3 1/2 years ago, apart from the chavvy stickers all over it, it was in decent condition for it's age
I would imagine, with so many bikes on site, you’re bound to get good uns and bad uns. Many people trade in absolutely mint machines.
Don't get me wrong, I've seen some shitters in there from time to time, but, there are some tidy bikes too
