Hi Cliff, if you go to "bikes for sale" on the MCN website, you will see new bikes advertised for just under £10000 without extras. If you look in used bikes on the Keith Dixon website you will find a new S10 for £10899 without extras and obviously cheaper than the £12899 one with extras if that makes sense.
However, I have had lots of dealings with Keith Dixon and is more than willing to negotiate with price reductions, extras thrown in for free or superb p/ex allowances.
I have recentlly bought a new s10 off him and got a really good deal, complete with many extras. Admitedly I've bought a few bikes from him over the years but have always been impressed at the way I have been treated.
Getting one for the cheapest basic price is never the full story. I have no connections with Keith Dixon other than being a satisfied customer.
Hope this helps
