I had a '57 Mercury. It was ugly indeed. Thats why I bought it, a black and whith 4 door that looked like Broderick Crawford should be at the wheel.
I can't tell one year Fiesta from another, although I thought they were sold in the US in '78, '79, and '80. I always thought that they were cuter than a Rabbit though. They were also the hot car in SCCA Showroom Stock Sedan racing for a time which gives them considerable style points in my book.
