In order to avoid mistakes, I suggest you have someone who knows all the details about cars. Also, make sure you get a full history of the car. As for customs broker, I recommend this website: http://clearit.ca. Check it out.
Look at the history of the car on Carfax and also go to Nada and Galves to check if you are at the correct price point!
The Chinese cars are cheap but if you choose wisely, they can work fine in your business logistic structure. If speaking about private usage, then I would rather take something more reliable. Anyway, if you are a QQ fan, you can find some interesting info about the vehicle here - https://listcarbrands.com. The site looks informative so I liked it.
