I myself am a huge fan of GNs. It's the small displacement and big output that really do it for me BUT to most people it's just an 87 Buick Regal. There is a fellow here locally that has a few dozen of them in various states from an untitled GNX with a few miles up to burned-out hull. He also has a complete building full of the guts to make one of these cars. Engines, trannies, tires, wheels, interior....he's an absolute fanatic.
Here's his most famous.
