Hi, the C-max is a mini MPV version of the focus as is the new Galaxy/S-max an MPV version of the Mondeo, MPV's are designed to be stable at motorway speeds whilst carrying a relatively high load compared to their saloon versions, the suspension design and stiffness that allows them to do this, also lends itself towards being a stable towcar.
Whilst many saloon and estate cars can be seen towing a caravan with tails on the ground and nose in the air, I have never seen an MPV like this, even with two adults, two kids, our ski gear, luggage and 200 bottles of wine in the back of our Sharan it was lower than normal but nowhere near on it's a*se
