This one is sort of based on the early "Sports Sedans" that were raced over here in the '70s/'80s . Very wild & very popular.
Floor & inner panels came from the AMT Cougar, body from the AMT '66 Mustang kit. Guards bent up from evergreen sheet with a little filler. Paint is Tamiya Camel yellow.
My type of race car !! Hope it works for you too.
