Ypu've gotta buy it Pete, CB1100R's are becoming very collectable. A mate of mine here in Melbourne has several and is a member of the CB1100R club in Britain. Every year he flies to England for the big Stafford bike show and is sponsored by the club, who pick him up from the airport, put him up in one of the members homes, take him to the show, then get him back to the airport for his flight home. He buys all the 1100R bits he can find at the show for his ever-increasing collection, and the guys ship it all back to Oz for him. Good blokes.
Anyway, when he was there last year he stayed with a retired engineer who, in 2007 used a big chunk of his superannuation savings to buy an extremely rare Honda NR750 oval pistoned beast with virtually no miles on the odometer. As expected, his wife went absolutely ballistic! He kept his head down and took her abuse, but had the last word when the GFC hit and his superannuation fund almost went belly up.
Had he not taken out the money for the NR he'd have pretty much lost everything, but in a couple of years time the NR will still be worth at least what he paid for it, if not considerably more. The "investment" argument may well help if you and the missus are looking at retiring in the next few years, and the occasional ride will be a lot more enjoyable than looking at your superannuation statements. Cheers, Terry.
