Damn man, that is heartbreaking. That thing was barely broken in, lol.. I'd be pissed if someone killed my car like that, for just not paying attention. I get it if it was weather related or something but to just flat out not look is punishable in my eyes. You're driving a 3-4 ton vehicle. Pay the F attention people!!
You have a right to be pissed off. Now you have to deal with insurance, their insurance and go through the hassle of finding another ride that you like. And you'll likely be sore tomorrow.
Maybe upgrade to a G8?
