According to Curt (Trailer Hitches)... they are waiting for a TLX to become available to measure up for as hitch.
Although towing is not recommended, I will install a hitch in order to accommodate my bicycle rack. Also we may tow a luggage trailer (400 lbs or so) if we decide to go to Florida for the winter. I do not consider this to be problematic for any car.
I expect that a hitch will be available by February or March.... if not.... I will offer my TLX to Curt to measure up for a hitch. I expect to have my TLX sometime late February or early March.
