This 1957 Packard Clipper Wagon is claimed by the seller to be one of 836 built and a factory McCulloch supercharged 289 V8 car. Another source says 869. Photos show a complete looking car, but surprisingly no engine shot is included. An amazingly restored example sold for $60k+ at RM in 2011 (link). Find it here on Craigslist in Chatanooga, Tennessee for $5k. Special thanks to BaT reader M R. for this submission.

The rear end design has a deeply recessed tailgate, which looks very straight. Replacement trim is likely impossible to find so it is good to see all the rare rear trim parts intact.

This car deserves to be restored. How many factory supercharged wagon models could there have been? Is this the only one?
