Must admit that my XC70 and Superb estate 4x4 were good tow cars and the solo drive was better than any of my SUV 4x4. The Superb’s load volume plus rear passenger space beat the Gen 3 XC70 hands down. And I am 6 ft 4 in I could comfortably sit in the rear seats with the front seat extended back.When we last changed our towcar, I wanted a 4x4 but didn't want the aerodynamics of a brick that SUV's have.
We have an Audi A6 Allroad which tows very well.
