Nope, but I have now, Thank you sir

. I also picked up some of these
CMK Wheels , and just in case any ones is wondering what you get essentially is 4 inside duals and no front tires :hmmm , don't ask me why. No matter the rear tires are ok and do look a bit better then the kit ones, how ever there are ejector pin marks? on the outside of the outer set :S
And Wow Cheyenne, Thank you.
I also came across this site which is got a lot of information,
Blitz Bus , if anyone is interested.
This one here depicts what you get int the kit for an interior,
mainly the wooden seats, which, if I'm not mistaken, probably indicates a built for purpose bus, where as most of the other ones look like the may be commandeered units or picked up already built and pressed into service as is. With this one in the pic the interior looks to be a touch on the dark side so if it is the exterior colour, it may be dark yellow and not Panzer Grey. Opinions most welcome.
I may just wait and order up that etch set before I go to far on this one....
