Viva Moto - the sales arm of We Buy Any Bike.co.uk - They buy them cheap and usually sell them cheap too, base their business on fast turn-around. You just need to be sure what your buying as at an auction I guess. They do annoy other local shops due to their low prices sometimes. I bought from them and you can haggle too even if the bike sounds cheap. Not sure what the customer service would be like if you had issues but I had a good experience buying from them. the 998 FE they had in (still did last time I looked) was the owners, but not priced as they usually do - else I would have had it, £10k a bit steep for an FE BIP I think.
Think I'd also avoid if it was run in on track, unless money was right. When I got mine, it had done about 1400 miles of which the ladt 500 were mainly trackdays. But still had warranty (year old) had some of the right bits fitted plus track fairing and spare wheels and was about right money. Have since done 2k miles, about 500 on track myself, and its lovely Firm believer in treat em mean, keep em keen with bikes as well as birds! Lol
Oh the irony. This statement should be plastered all over every USA billboard so they finally understand what it means lol
