I plan on some test driving, just wondering if there are any options i'm missing. WIth my work driving schedule and the fact that I get to write mileage off on my expenses I will probably rent one for each of my next road trips and use the mileage money to effectively pay for "extended test drives" assuming I can find places that rent some of these.
If you can swing it, Mercedes-Benz S-Class (S550) would be ideal for over the road work. It should fit everything but Android Auto(?), and that may be able to be added after market. Most importantly, the cruise control for the newer ones (I think 2010+), can also do some pretty nifty things, like speed matching, and assisted braking. Which, if you are doing conference calls while driving, could save your ass.
You might be able to find some good deals on a used S550. Here are the current price I pulled from Manheim (Black Book):
2012 S550 average $35,000 @ 48,000 miles (10 cars sold in last 30 days)
2013 S550 average $39,500 @ 49,000 miles (19 cars sold in last 30 days)
2014 S550 average $58,000 @ 34,000 miles (45 cars sold in last 30 days)
Edit: I dont own one, but I have talked to an acquaintance about theirs before. The major downfall seems to be the maintenance costs. Other than that, they said the cruise took a bit to get used to, but they dont want another car w/o it and it is one of the most comfortable cars they have owned.
