Bought my "Broadlands" on EBay about 15 years ago for I think, £22. What made that even better was that the seller was only about 4 miles away so it was cheaper to collect it than have it posted. It's one of a lot of things in my collection that I'm glad to have bought when I did.
Had a browse on ebay earlier, call it nostalgia if you like. Last time a few years now you could pick up a decent example for twenty five quid, now fifteen is wanted just for an empty box...
To get a livery that the "current" Hornby releases don't offer, perhaps. A body swap is simple and the Hornby chassis offers slightly more modern facilities.
