Trailer Hitch for 2004 A4

Hi,
I searched the forums and read that putting a trailer hitch on an A4 is a sin, but I was thinking about doing it since it'd be practical for me.. Is it a sin because it's unsafe or because it just looks bad and weighs the car down? I'd like to do this since I'm moving for school and will be making relatively frequent trips with a good amount of stuff to move.  Can anyone tell me if putting a hitch on the car is feasible? Are there any recommended brands that will make it more aesthetically pleasing? Thanks in advance for your help.

I just threw up.........
 
Wasn't the tow package an option for the B6?.....LOL

U-Haul.
