Lexus' most popular model has gotten some changes for the 2015 model year. Before you get too excited, the changes for the 2015 RX are very minor. For starters, the entire RX lineup will get the seven-inch display audio system with backup camera as standard. Options include new nineteen-inch alloy wheels that are treated in a light-grey finish, along with HID and LED headlights and foglights. The F-Sport package comes available with a new Cabernet-red leather interior to amp up the sport.
