I had a Power Wheels toy for my girls when they were 2 and 4. Now that my son was turning 4, I didn't want him driving around in a pink Barbie Jeep. I went and bought the Ground Force but it is significantly faster - the Power Wheels tops out at 5mph (but also allows you to lock the speed to a max of 2.5mph), whereas the Ground Force has a max speed of 12mph. I must say though, that I (a 40 year old man who weighs 165 pounds) LOVE this thing...It was fast, nimble and my neighbors got used to seeing me drive around the neighborhood. But, ahem, where was I? Oh yes, back to the kids. My 6 and 9 year old daughters love this car since it is significantly faster than their old Power Wheel car. I was even able to take my 6 year old out with it when I went roller blading and she was able to keep up with me and then some (we went out for about an hour (so figure we went about 8-10 miles since we weren't going the full hour. That being said, it is way too fast for my 4 year old...and even my 6 year old who knows how to drive was doing a series of figure 8's in the street at max speed and loving it...when she lost control and ran full speed into the curb...she was NOT a happy camper, although she wasn't seriously hurt. The car does sit low though...so if a child were to run under an SUV...there is a very real chance the child could be seriously hurt though because their face would smack into the bumper...so PLEASE be mindful. I allowed our friend's daughter who was 5 to drive the car in an very open field and she loved it...but ended up losing control as well and running into a play structure. She hurt hurt herself and broke the seatbelt because she panicked and went full speed into the structure...she wasn't seriously hurt...but I have definitely re-thought my stance about letting ANY child under 8 or 9 drive the cart by themselves. Because there is no way to lock out the max speed...the children should be very carefully supervised. I do drive my 4 year old in my lap (and even drove him to pre-school one day in the morning (which he loved btw). Of course, I did look a bit stupid driving home in this go kart in the morning near the school...but my son was VERY excited! ;) Please please be careful with this car with young children.
