I have noticed that too about the road show dates. The initial dates evidently were much broader, presumably to handle flexibility in the end. In my case, initially the INDY tour stop was listed as July 6 - 11th, with test drives on the 9th and 10th.....but ultimately that was switched to 6th - 8th (fri - sun). Good luck with your test drive - hopefully being at your own MB dealer, you can get to spend more quality time with it. In our case, there were easily a 100 people there, and the wait was about 2 hours - in the hot outdoors!
