I learned to drive in my parents 1973 Gremlin with the AMC 232 cubic inch six. Other than the excellent (for its day) corrosion protection, this was truly a horrible exercise in automotive design and construction. I can see buying a scale model of one for nostalgia (some toy company actually makes one - I saw it in Wal-Mart!), but can't imagine subjecting myself to owning a real one, let alone paying for it.
Strangely, this might make an interesting tow car: with a real engine swapped into that big engine bay and very little rear overhang (since a Gremlin is a Hornet with the tail missing), it could tow okay; with storage space in the trailer the lack of cargo space might not matter.
Since the eBay car is an "X" model, it probably has the more desireable GM 258 cu in engine. Maybe it even has front disk brakes
; ours had drums all around!
