TEST-DRIVING THE Power Wheels Mustang for kids. I would have liked an electric car when I was a kid. We got the Insta-Daughter a Barbie Jeep when she was 3, and it went over very well. When she outgrew it, we gave it to a nephew, whose dad converted it to an “Army Jeep” with a can of olive-drab spraypaint. I don’t know what ever happened to it after that, but it certainly held up well.
