Hoping this post is still alive. I have the same car. It came with a detachable towbar (thanks.) I need to buy a 4 bike cycle rack. Do you think the weight will be an issue? and also: It feels like there is a fitted socket up behind the bumper, Does that sound right? and if so how do I access it? Does it drop down on a hinge? Or do you just attach as is? Hope someone out there is listening... Thanks Shaun
