Not quite .
Actually , it was a cut lenght Matador( compare all three relevant sets of dimensions) intended for a GM sourced Wankel that was never produced .If it had worked out , it was intended to take over the Hornet/Gremlin "slot" .
The Wagon was actually kinda neat - definitely better looking - although impossible to fully cool in bright sunlight and high temps .
#6 was a "Boys I'm Taking Charge Here" to change (read between the lines) - the backend of the 258 I6 (can't remember if the 232 was offered - or for long???)- was buried waaay back - never intended originally for the car .( I helped someone exactly once on this - and she was more than pretty .)
I may have this slightly wrong and I can't remember which body style , but one of them was credited with something like twice the weight as was "average" ( I believe compared to other Domestic intermediate "class") in glass weight .
They were also originally designed to an anticipated impact standard (somewhat like a Fiat X 1/9) that never materialised .
Bottomline : somewhat heavy - although I did know one individual who removed most of the glass , rearranged/removed/replaced a significant amount of metal and was suspected of having installed either a FORD 221-260V8 from who knows where or possibly a BOP 215 - it wasn't AMC or Chrysler .Nobody was allowed to look .
