The Greased Gremlin was designed by Larry Wood. It is based on an AMC Gremlin, heavily modified in the "pro stock" drag racing style.
This casting first appeared in 1975. The model number 2502 corresponds to a 1979 mainline release with Blackwall (BW) wheels and updated graphics.
The casting has the characteristic pro stock look with a huge engine and hood scoop, a low front end, and massive rear tires. The 1979 version typically came in blue with red, white, and yellow graphics.
It is a direct counterpart to other pro stock castings like the "Flat Out 442" and "Hare Splitter." It is a heavily modified version of the "Gremlin Grinder" casting.
The initial 1975 Redline version was red. The casting has been released in many different colors and racing liveries.
