I've been struggling for a 1:48 London bus.
There is ones out there, but they're really expensive. I tried eBay and came up with this....

A cracking model for sure, but......

It turns out the seller gave the wrong description! I've managed to find this when I was coming back through Gatwick recently.....

It's a money box, but I reckon I can make it look the part. I just need to change the wheels, fill in the money slot, extend it in places and change the bonnet! I think it'll be worth it!
