I was reading through some of the comments on the Auto Salon kei car post, when I realized that we haven't posted anything about the Suzuki-built Autozam AZ-1 that was sold by Mazda during the early 1990's. It was basically a kei-sized version of an exotic car, complete with an MR engine layout and gullwing doors. With less than 5000 built, they are extremely rare and I've only seen a couple during the past year I've been Japan.
I found this photo of Watanabe and fender flare-equipped version on a Japanese owner's site called Advent. Check out the site for more photos of cool AZ-1's.
