While browsing eBay (mostly for older Majorettes, Matchbox, and Tomica), I came across this Plymouth Voyager model, which appears to be a dealer promo.

I have to say that I am at least a bit interested, though the panel gaps for the opening sliding door appear to be worse than the 1:60 Matchbox version, and the wheels are rather iffy. Shipping to where I am (Canada), at $16 USD, is expensive, as any larger model would be, though it doesn’t appear too unreasonable - there are countless sellers charging the same for a simple HW or MBX.
