Just wondering whether that would be better than ebay/classifieds.

I know someone that used it and they got a good overall deal.

Remember they have to sell the bike on so are never going to give you top dollar for it.

I'd imagine its a bit like p/x your car: you know you'll get more selling privately but its much less hassle.

I 've used it

I traded in a Cannondale prophet (800) against my Trek Remedy.
Only got £300 for the prophet, but it was 21/2 year old, never been serviced, the rear hub was making some funny noises, and it was basically the stock bike. Also new prophets (with pikes) were going for £1000 new so wouldn't have got much more for it.

The work i would have need to do to sell it on the bay wouldn't have been worth the effort (not sure how much a lefty service is but it wasn't very plush in the end)

Picked up the Trek last year in the sale, and go 0% finance over the year. so worked out well in the end
