was it E30cabrio who went to meal-piece route with the tow package? it might be more beneficial to go with a brand new tow package for about $500 in parts (if you can find one), as this way you will have all the pieces together... But, if you know what to pull from a junked X5 with the tow package, go for it... might be much easier than i imagine...

Nevertheless, this is one immaculate truck, with manufacturing date of 7/2006, definitely one of the last IS's made... I was looking for something like that in 2012...
