 I am enjoyed the cars from the day we bought it. I knew it was going to be on her powered but I was okay with that because of the size and the Comfort level. Unfortunately now it is winter time in Iowa. Any kind of snow event the rear rims have at half inch of snow that gathers inside of it and throws it off balance and you can not go over 50 miles an hour without having a severe vibration. We have multiple other cars and I've never had this issue before it just looks like a poor design on the of the rim
