This is a neat concept with the wheel inside the D, and i like the way you did Donald Auto Group. I do not think the wheel is representative of the luxury brand through. Remove the D and Wheel and use another element to the left and this one may move up as it will be easy to reproduce on various materials. Maybe a road element and on the far left of the black line white boxes added to look like the end of a checkered flag.
I like entry #135. Can you add www.DriveDag.com and change auto to Automotive. Also the customer had a last minute change of heart and would like a royal blue similiar to Volkswagen. #15317E is very close
