Picking up my new cc tomorrow and was surprised when dealer explained Volvo doesn't offer an oem option for the v60 and they (dealer) don't offer install of aftermarket parts. 3500# Towing capacity is a selling point to me in this segment and bought me to Volvo. So this seems like odd choice on volvo's part. Any experience here with specific aftermarket options or tips for DIY install on this model? Any real world insights will be a help to me and those that come after.
