I've been towing my Ventus in a lift-top trailer with a 1.9 liter TTiD Saab and automatic transmission for the last couple of years, and extensively through the Alps. No problems with stability whatsoever, and the engine has lots of torque to accelerate beyond speed limits uphill towards a mountain pass. On the highway, I typically set the cruise control to 75-80 mph. 33 MPG.
