I have used DAS twice and have been very happy with them.
With DAS you can pay extra to get the car shipped in a closed container
You also can pay an extra fee for guaranteed delivery date.....
My most recent experience was to ship a E55 AMG Wagon from Maine to WA State.... They picked the car up from location on time and it made it to Seattle a day earlier than we were promised.....
I highly recommend DAS.......and their customer service is pretty darn good.
