This is a Sunbeam Funwagon. You’re probably never heard of it. Per the seller and like one other online reference, Funwagons were based on the Sunbeam Commer FC Van, a small British van from the Rootes Group. The Wikipedia article for the Commer FC confirms my assumption that all old British vans make like 50 horsepower and top out at about 65 mph. Obviously that platform needed extra weight, drag and a raised center of mass, so Sunbeam added a motorhome body and attempted to sell it exclusively to Americans. Those would be the same Americans just beginning to make use of the Dwight D. Eisenhower National System of Interstate and Defense Highways at sustained high-speed straight-line cruising. In a 1500cc-powered, narrow-track, high-roof camper thing. Right.

To its credit, the Funwagon has no fiberglass (that skin is sheet aluminum) and this one is completely mechanically functional. Supposing you were into silly, underpowered British vehicles (a few of our commenters come to mind), the $3k current bid isn’t too ridiculous in that it’s a typical price for an OK condition example of a rare vehicle. I was thinking motor swap, but it’s not like the original transmission or axle would be up to bear the necessary power boost. So, complete drivetrain swap? I’d offer up a Toyota 22RE + W56 + 7.5 or 8″ rear axle.

Your thoughts? Epilogue: I meant to schedule this for last Thursday, but somehow screwed that up, so it never ran. Since then the auction ended with a winning bid of $6799! 1967 Sunbeam Funwagon for sale – eBay Motors
