We are considering purchase of an F10 535i xDrive for my wife. I can't find a trailer hitch for this car anywhere on line and our local dealer, while very helpful, has also had no success. We keep a small boat at our vacation house and need to tow it about 50 yards to the ramp where we launch and retrieve it. We currently tow the boat about 7 miles each way to a gas station about 2 times a year, although this trip is not absolutely necessary. The boat and trailer weigh less than 1500 pounds and the tongue weight is less than 100 pounds. Any suggestions? Thanks for any help you might have.
