Congratulations and welcome.
How far along in your dinghy considerations? (determined how you want to tow? Dolly or four-down?)
Considering purchasing a vehicle specifically as a toad, or just want to use one you already own?
(We dolly tow mostly so we can bring along either of our cars and to minimize the modifications necessary--in the case of a lease car.)
Some cars you may consider, if you haven't already: The current Ford hybrid and plugins (C-Max Hybrid, C-Max Energi, Fusion Hybrid, Fusion Energi, and Lincoln MKZ Hybrid) all can be towed 4 down and the Energi versions can get 20+ miles from plugging them in.
Although Jeeps seem to be the most popular option for towing four down.
