audi s4 avant b7 '56 reg' towbar??

[MARKS4]

I have not long had the car and to be honest I love it!! fuel consumption is sh!t but you dont by the s4 to see how many miles to the gallon it will do!!
I am looking into putting a removable towbar onto the the car, firstly can you get a towbar to fit the s4 avant as I cannot seem to find one on ebay, they all seem to say 'except s4 +rs4' can you fit a towbar from an s line quattro or are they different? I have also seen something about extra fans?? Any help / advice will be greatfully received!!

see my how to guide in the audi area of the how to section.

Seen the how to mate, cant fault it! My problem is that why people do not advertise the towbar for the s4 / rs4 - If 1 of the other towbars fit which 1 do I go for? Do I go for the quattro s line ? Just not sure why the s4 doesn't come up when I search for the towbar?

Unsure.

I can only guess that it may have something to do with the rear bumper differences. Compare an rs4 and s4 bumpers with those of s line and se.
