What is the rated towing capacity of a Mazda 626. I have a 2001 Mazda 626 LX (4-cyl, automatic) and I want to know if I can install a trailer hitch and tow a small trailer with a 400 pound motorcycle. The hitch rating for the 626 is a class 1 but I cant seem to find what my car's towing capacity is.

Thanks,
E
