You can tow the 2010 - just follow the emergency tow procedures - see http://www.remcoindustries.com/Towing/Store.php
I bought a tow dolly last year - used it about 6 times. It does work but no fun to hook up when it is raining or in the middle of the summer. I found out I could tow my 2006 Honda Civic 4 down - got it setup last month. Made one quick trip - I think I am car tow heaven.
Will be selling my tow dolly(listing in local classifieds) soon.
Guess my point is - once you tow 4 down, you won't go back.
