I keep this folding cart in my SUV I am not sure about the plastic parts but so far it has held up just fine. I took it on a two-week road trip and used it every day. Its main use was a luggage cart at the hotels. No more hunting down a cart and returning it back to a lobby. This cart did just fine for the Ice chest and luggage I was moving. The bungie cords were a must have and a few extra would be a help. It prefers to be pulled, pushing it was not an easy go. The wheels are a minimum size and sometimes had trouble going over a lip such as a low curb or misaligned elevator entrance. All in all I would recommend it for what I used it for.
