I have the Pontiac Vibe, uses the Toyota drive train. Get 28 mpg around town and 33 mpg on trip to southern VA from PA at speeds above the limit but below 82mph. I had placed 3 bikes in back. Had to remove front wheel and took pedals off bottom bike. Just laid them down with a moving blanket between. One bike, such as your Ruby will fit in nicely with wheel still attached. Picture shown is the real thing, Toyota Matric. I don't know about the chick magnet. At our age the magnet is usually an obvious show of extreme wealth. But the bright blue shown or bright red will certainly attract attention.
