Just in case anyone is interested I spotted a DL1000K6 GT on an '06 plate, in black for sale in M&S Motorcycles in Newcastle (
http://www.mandsmotorcycles.co.uk or telephone 0191 2610121). Just saw it today in passing, looks nice & tidy with the full Suzuki luggage and appeared to be totally standard. No price on it or any idea of mileage as it looked like it had just literally gone into the showroom.
P.S. it doesn't look like they update their website that often....
