Even with the present/previous K3, it was hard keeping up with demand, so must have been doing something right.
No the older K3 cannot be upgraded to the complete K6 version, for various reasons I don't understand, but nice to see the new improvements to the K3 coming on line also, shows they're commited to all users past and present, old and new sort of thing.
Biggest selling point for me is the attitude of the staff, nothing is too much trouble, always happy to go way out of thier way to help where they can, some of the "finished" ready to be mapped cars are a long way short of this, but all sorted out effeciently by dedicated staff who don't just see a £ sign, when they see a customers order, many agents around the country also.
