Not many were made, but the AMX was a true performance car. Available with a high output V8 and a tricked out auto transmission or a beefy 4 speed.
The Gremlin wasn't a beauty contest winner, bun not many cars of that era were. The Gremlin was a shortened Hornet. Very safe, especially for younger drivers, in that it was heavy and had a lot of metal protecting the passenger area.
The 232 cid 6 cylinder would easily go over 200,000 miles, and the chrysler transmissions were bullet proof. Just keep everything serviced and it would get you there and home again every time.
As far as AMC being ahead of its time, don't forget the Sportabout. It was a hatchback 4 door mid sized stationwagon. Several manufacturers make a clone of it today, including Mercedes Benz.
