I have had a Citroen C5 2.0 Hdi VTR and towed with no problems for the last couple of years although I have just replaced it with another Citroen. I remember reading about the filter replacement on this forum some time ago but could not find any mention of it in my handbook so I suspect it may only apply to pre 2005 models. Anyway, for the money I don't think you will find anything better as a towcar, great stability, and self levelling which I found a big plus.
