As you may have seen from my wanted post in the classifieds I'm currently in the market for a k3. I haven't seen one in the flesh in a while and a proper look around one would be useful so was wondering if anyone nearish Oxfordshire (50 miles?) has a k3 I can come and see. Don't mind if it's off the road but reasonably complete would be ideal as quite tall (6ft) so want to make sure I'll fit!

Can not help you regarding looking at k3 as sold mine a few years ago but can tell you that you should fit no problem as I am 6 foot 2 inches and fitted just fine.
