I buy a large SUV so i can survive a mobile phone users head on collision. Having had 3 run into the rear of my car in the last 10 years, it also needs a hard rear end.
I could easily manage with a small car as most of my journeys are local now. When i do a 400 mile trip though, i appreciate the very low noise and soft ride of the monster SUV. One day, i will get out of town in it. 1000 miles now at 3 months.
