I recently noticed that behind the grill lights are threaded receptacles for towing. Do these take threaded eyes, what size, where can they be gotten? Can the auto trans cabrio be towed four down, if so, how far? Thanks, Mick

 

Towing eyes are normally in the boot next to the jack. I don't know if they are the same thread on all models, Google them.

 

You need to check the owners manual about towing. Most cars cannot be towed 4 on the ground, you need a tow dolly. I would say absolutely you need the tow dolly for an automatic trans. I don't know about a manual trans. The problem is lubrication and rolling the gears without the engine running to provide lubrication...
Check the owners manual, if you don't have it, you should be able to find it online.
