I bought one after seeing discussion about it on Missing Lynx a while back. Interestingly, the (WW2) Tiger expert, not knowing it was a modern armored car, was mystified that a model manufacturer would attempt to produce a model of a Tiger with interior without consulting him.
Any way, an eBay seller named Model_Space has them listed for $18.99 + $13.80 shipping from China. He keeps relisting the same auction every time it sells. Sometimes people bid it up above $20, but the last few times, no one has bid. I have been considering buying a second one and have been following the auction.
