Sorry dude, she's right. They didn't have any diesel VWs for sale in the USA in 2007. It's a GTI, and my fuel economy average is about 22.6. And it requires Premium.
I got a ride on the back of a bosshoss trike yesterday. I'll have to ask the Old Grump for the exact specs (I dont know shit about this kind of thing) but motherfucker that shit was FAST.
