The Tig doesn’t have any side mouldings which will stop doors from cars parked next to it from opening and causing a dent in the door panel. Does anyone know any alternatives?

I have a friend who owns an X5 who got side steps installed to stop this from happening. He often parks next to cars lower than his so that if they should swing their doors open it would hit the side steps first before hitting the door panel. Problem is I’ve been quoted about $900 to install a genuine side step to the Tig!!

Has anyone had generic side steps installed in their Tig before for a much better price?
