MCN thats where I bought my GS 1150, 100miles on the clock.
But it took a while to catch the wrigth one, you need to have your cash ready in your hand, NOTES they smell good.
Test ride bike, as a pillion.
And trust your nose, you should know a dog, before it bites you.
Ask another GSer to come and see it with you and make sure he doesn`t buy it before you.
