To find the exact towing capacity for your Buick Regal, you should:
* Check your owner's manual: This is the most reliable source of information. The manual will specify the maximum towing capacity for your particular vehicle.
* Look for a sticker: There's often a sticker located inside the driver's side doorjamb or on the glove compartment door that lists the vehicle's specifications, including towing capacity.
Without knowing the year and trim level of your Buick Regal, any number given would be unreliable and potentially dangerous. Always refer to your owner's manual for accurate information.
