I didn't know you could put a tow hitch on the S4. How much can one actually tow with it? I can't imagine it's the best idea...

just stuff that comes up...

where you there at 7 am when I was?

Although I probably should. Traffic wouldn't suck as much.

The limit for towing is still the car's frame... So I believe that the S4/A4 can tow the same (about 1000lbs which isn't much)...I would only tow something like a track trailer, will track wheels and tools.
