Robert Q. Riley Enterprises

How'd you like to tool around town and get 225 miles per gallon in one of these?

Robert Q. Riley Enterprises will soon introduce its XR-3 plug-in hybrid, a sleek two-passenger, three-wheel sports car.

Designed to be assembled by someone "with average mechanical abilities and no prior experience," [ed. uh huh] the all-wheel drive vehicle will be available as a kit or plans for complete do-it-yourself construction.

Riley says this new vehicle is a new category of personal mobility devices that are neither automobiles nor motorcycles.
