I'm changing my car and need to sort a tow bar on the new one. In the past I've had fixed swan neck aftermarket and retractable factory/OEM tow bars, this time I'm going for a removable swan neck type. There are various manufacturers offering these (it's for an Audi A6 Avant) but I know from experience with my parents cars that some detachables are a bit fiddly to remove/refit. Anyone have a particular brand/design of mechanism that they recommend or any to avoid? Thanks
