And the car to the right, that is behind me is the real sized one. Just love Photoshop. All fun.

32mpg, but I'd expect with a modern 1.1 to 1.3 liter engine (e.g. from a Honda Jazz/Fit) it would be a LOT better. The photo appears to be fake, but it's still cute and the car is real, just resized to be smaller. It's a comp of the scene without the car and the car parked there. The reflection of the "hobbit" word on the car doesn't have the 't' obscured by the foot of the gentleman.

What kind of gas mileage does it get?

The bloke looks like Dubya.

Maybe a Wolseley Hornet - same thing, different badge/name.

Normal size I think it would be a Riley Elf, a version of the Austin Mini with a different grill and extended & restyled boot.

What car is that?

I love it! The "L" plates are an extra special touch.
