Got a Putnam Hitch on ebay and it took less than 2 hours to install it on my 06 3.0 with Aero Pkg. I looked at the article here but didn't have to do many of the things mentioned. I didn't have to drop the exhaust at all. I have no options on my X except xenons so I didn't have to deal with park distance control or anything like that. Maybe the 06 model is easier than the past ones when installing a hitch?
