Just bought an XR, but it doesn't have a sunroof nor does it have 4-wheel drive.. and my friend asked me: "but isn't that what XR means? (has a sunroof and 4-wheel)?" So it got me thinking: WHAT DOES XR MEAN?! Why's it more expensive? Any help is GREATLY appreciated, as I hope the Toyota salesman did not lie about the car I just financed.
