For sale is a practically new set of OEM roof rails and cross bars and all associated parts (part number CAB000040PMAG). I bought these a couple years ago from Atlantic British for ~$1200, had them on my (always garaged) RR for about a year and only used the cross bars once to bring home a Christmas tree. Shortly after installing these, I bought an LR4, which now serves as my Christmas tree-getter.
The rails and crossbars are located in Summit, NJ and are for local pick up only, as they do not ship very well. Atlantic British had to send me 3 different sets, as the end caps on the first two sets both broke in shipping!
