There's a 2007 here. Seems identical. Yam 15hp 4stroke, trailer (Bramber, so good make) http://www.bhg-marine.co.uk/preowned.htm

They are asking £5500. This BHG shop seems quite expensive though, so I think houghn's analysis is right. BHG are, for example, asking £6500 for a 2003 Avon 320 jet and I can assure you that they are worth nothing like that, having had a 2004 DL model (so better and more exp that the one BHG are selling) for sale at €4000 for a few weeks with no takers.
