I have never owned a Duster or a Demon or a Dart Sport for that matter (essentially all the same cars)- though I came close a couple of times. The Hang Ten was one of many wild and wonderful decor packages Chrysler made available to peddle their otherwise standard A-body production cars. Orange colored shag carpeting, stripe patterned seats, red white and blue exterior striping, and the requisite fold down rear seat (for your surfboard, of course) when combined with a EW1 Eggshell White Duster made the Hang Ten package.
Technically, this car is not a Hang Ten, but falls into another group of painted-up Plymouths that share a common gene with the Hang Ten cars. This car actually has the even rarer A63 Cloth and Vinyl Decorator Package, along with a whole lot of other cool options like the 318 V8 engine, AC, PS, Disc Brakes, Rallye Wheels, 8 3/4 Sure Grip rearend, bucket seats, sport mirrors, full gauges and floor console. Combined with the great color combo of black with white 3/4 vinyl top and red/white waist stripe, it makes for a pretty cool car.
And how does any of that translate into value or even rarity? Unlike most domestic car manufacturers, Chrysler's cars received coded fender taqs that document each and every individual option as ordered new for that car. That set the stage for a whole cottage industry ( and accompanying value system) of de-coding such tags and identifying rare factory options on individual cars. The nuttier the option or combination of options as originally ordered- the rarer the car. Or so goes the Mopar game.
But all that- if it proves out- is just a bonus. I think it is a neat looking car, with some nice driveability options, offered at a very fair price of $3500. Lets hope this surfer spent plenty of time away from that salty sea air.
