The Concours d'Elegance at Cranbrook has quickly grown to become a significant regional Concours. While Cranbrook isn't nearly as comprehensive as some of the more established Concours, the 2005 event was definitely a worthwhile visit for car enthusiasts. Significant marques from the early 20th century at Cranbrook included Duesenberg, Bentley, Packard, Auburn, Pierce-Arrow, Talbot Lago, and many others. A display of unique GM concept cars from the 1930's-1950's were a highlight of the Concours.
