The 1950 Buick Roadmaster was billed as the perfect car for middle management, an entry-level luxury sedan with room for the whole family and enough panache to make your Ford-driving neighbors just a tad jealous. It was a pretty cool car back in its day, though these days it wouldn’t warrant more than a single look at most classic car shows, at least in stock form.

From the front seats forward, this 1950 Buick Roadmaster is par for course, but behind that is a custom wrecker body that converts the Roadmaster into a Towmaster. Found on Hemmings, this odd rod predates both the El Camino and Ford Ranchero as a car-based truck, and the hidden tow hook makes this the perfect starting point for a diesel rat rod project if you ask us.

There is precious little history behind the Road/Towmaster, though the car looks remarkably complete and according to the seller, it starts and runs just fine. The wrecker boom retracts below two custom floor panels in the truck bed, and it was supposedly commissioned by a Buck dealership around the Oakland, California area. It’s undoubtedly had a long and weird history, until ending up in dry storage as part of a weird car collection.

Undoubtedly this Buick attracted a lot of attention, compelling the previous owner to ask $1 million for a car he almost certainly didn’t want to sell. The current owner has much more modest aspirations, asking $45,000 for the chance to add this one-of-a-kind Buick wrecker to your collection. It’s a car that comes around once in a lifetime, and that long Buick hood is just begging for a Cummins or Duramax diesel swap.

Even if it was just left as-is, the bewildering uniquity of the Buick Towmaster should make it an attention magnet at just about any car show.
