toyota carolla, toyota scion xb
Yes they both get good fuel economy, no neither of them is a large car. He had a Golf already, its bigger than the xB, and probably has more room than the Corolla - if you want a car in this class, wait a year and get the new mkV Golf TDI. It'll be sick, but seeing as how you are a dubber already - you know that! (I'm on VWVortex too, btw SN: Chronogoof89).
