Bigger vehicles in general are safer than smaller vehicles. If you are in a 2,000lb car with a 5 star safety rating, you will still probably be killed in an accident with a 6,000lb truck that has a 3 star safety rating. Despite all your advanced driver aids and BS. You will die, and the 1995 Ford F-250 owner will walk away. Mass is the most significant safety feature you can buy. Don't let some journalist in a suit tell you any different. He only wants you to drive the Corolla because he's driving a Suburban.
Personally, I buy cars based on my enjoyment of them. To buy a car for any other reason is silly. None of your friends or family will remember that time you got 55mpg on vacation, but nobody will forget the adventures you can have with a 4x4 on 35's.
