Meet Ron Borher, a man who has been a Mercedes-Benz technician for over 49 years. When you have been collecting as long as Ron, you tend to have some hidden treasure. Among the Chevy pickups and Toyota 4Runners lies a true unicorn in Ron's Mercedes Benz line-up, a 190E 2.3-16. This particular model is special because it was the only fast version of the 190E ever offered in the United States.
