hi twinpop, you need to keep searching the private adds for one but my advice is stay patient otherwise you might be tempted to jump in and buy something that's not right for you and expect to pay in the region of 3500-4500 i think. There arnt too many differences between an se model to the sp so i wouldn't rule one of those out, sure they have nice wheels but weight difference is negligible and your not going to notice the difference on the road.
Where abouts do you live in lancashire?
