the 1979 Porsche 924 Sebring was built to commemorate the victories at Sebring with a car that regular people could buy, so they took the absolute slowest car they sold and slapped a few stripes and stickers on it

and it was powered with an AMC Gremlin engine. 

The Porsche 924 Sebring 79 is, essentially, the base-model 924, powered by the VW-designed EA831 four-cylinder, 2-liter engine that was also used in such performance luminaries as VW LT delivery vans and trucks, the 1979 DJ-series Postal Jeeps, the Audi 100, and, yes, the AMC Gremlin.

and it was built with VW parts bins stuff…
