Darth Vader, your limo is ready! This is another odd-mobile for the aficionado, and I totally dig its angular death star aesthetic. Released in the depths of the '80s, when the words excitement and cars were never used in the same sentence, the GNX was the only real bright spark in US motoring. Always dressed in black, the GNX was the top-of-the-line model (above the Grand National), and with its high-po turbo six and loads of unique components, it hauled '80s ass. Yeah I know, it's not beautiful, but I just dig this black bomber. Another super rare car, the GNX is highly coveted by collectors today.
