The AMC Gremlin looked like a shortened AMC Hornet, with a distinctive, somewhat boxy design. Key visual features included:
* Short wheelbase: This was its most defining feature, giving it a stubby appearance.
* Fastback styling: The roofline sloped down to the rear.
* Boxy body: It wasn't rounded like many cars of the time; it had fairly straight lines.
* Small size: It was significantly smaller than most other cars on the market at the time.
While there were some styling variations over the years, the overall impression was one of a compact, somewhat quirky, and arguably unconventional car for its time. Images of the AMC Gremlin easily found through online searches will give you a good visual idea.
