There aren't very many wagons on the market, but this body style is a great choice for people with larger pets who don't want to drive an SUV. The 2010 Volvo XC70 is one popular model in this segment due to its people- and pet-friendly features. As a company known for its top-notch safety, the XC70 comes with a long list of standard safety features as well as optional collision warning and lane-departure systems. For pets, it features a crash-tested pet barrier, which will stay in place even in a 40-mile per hour collision with 4,000 pounds of force. The barrier, which is bolted into the vehicle, must be installed by a dealer. People-pleasing features include two integrated child booster seats, standard all-wheel-drive and a choice of three, fuel-efficient, six-cylinder engines.
