Cen has a rating of "F" with the BBB, it is the worst rating you can get:

"We strongly question the company’s reliability for reasons such as that they have failed to respond to complaints, their advertising is grossly misleading, they are not in compliance with the law’s licensing or registration requirements, their complaints contain especially serious allegations, or the company’s industry is known for its fraudulent business practices"

I can see why after owning a CEN MG 16. It's too bad because it's a fun little truck and it screams when something's not breaking off. I bought it for my son and it's been sidelined so many times he's lost interest in it. I bought a used MG 16 so we could chase each other around but the plastic is so brittle I have been pulling parts off the used car to keep the newer car running. I would never buy a CEN product again, I'm just going to run it until both engines die.
