Hi. Matt here. I am daily driving a 1979 AMC Pacer Limited Hatchback in Kenosha WI. 258 auto. Alpaca Brown. It is a really fun car to have.
I have seen 2 AMC Spirit Limited Liftbacks. One was stacked on top of another car in a boneyard. It was either a 79 or 80 model. It was a bronze/brown color. (My 79 Pacer Limited Hatchback is the same color.) The Spirit had "Limited" emblems on both front fenders. The other one was a 79 with a 304 V-8 option. Again, it was a bronze/brown color. These Limiteds are loaded with factory options as part of the Limited Package.
There were also Concord and Eagle Limiteds that I have seen. Also, Jeep had Limiteds starting in the 1979 AMC/Jeep model year. -Matt.
