I would say most collectors feel if a car was not sold through or delivered originally to Baldwin Chevrolet then it would be a Motion car. A new car sold though Baldwin as a Motion modfied car commands a premium versus a car modified by Motion only. I don't understand the logic of something being called a BM car is it never had any relation with Baldwin Chevrolet. I understand why they would want to call the new ones BM cars, but that in my opinion is to add value eventhough Baldwin is not involved. Baldwin Motion or Motion only, they are all great cars and highly desirable.
