Tandem seating + handlebars + 3 wheels = motorcycle trike or sidecar rig
Side X side seating + steering wheel + 3 wheels = CAR
Slingshot does not meet FMVSS, DOT, NSTA requirements for a "car".
Several states are already refusing to register these things as not meeting the requirements to be either a motorcycle or a car!
Might want to be one of the few to get one before they quickly fade away. Make sure you get one that has had the steering fixed!
Just an opinion, YMMV
BTW, the motor is the same GM 4cyl that was used in the Solstice/Sky vehicles that, IMHO got terrible gas mileage for small 2 seater vehicles. 25mpg was the realistic mileage!
Having said all that, would love to have one!!!!!!
