Rob, this is one of the most desireable and expensive Bandai kits on eBay. They typically will go for over $50, often up to $65-70. It's a pretty good kit, could use some PE detailing (don't hold your breath on that), but it appears, from a very primitive comparison to a few photos from Beltring, that it is basically accurate, and with that you can always improve it. In 1/48, there is no other model of a British pattern truck available except for the AA resin kits, for another $15-20 over the usual eBay prices for the K5. If I were you and I built British stuff, i'd build it, but if you sell it, you'll be able to buy 2-3 average price Tamiya kits....

That said, I want to build Brit stuff, so I have five Bandai K5 lorry kits and one K5 6 pdr portee from Wespe.
