A pair of Thule square roof bars for the previous model 169 Panda. I believe these will also fit the current Panda Cross, but you'd need to check I think. They've been used only a few times and I no longer have that model Panda, so these are cluttering up the garage. New price seems to be £126 (as per below, option A), so these hopefully represent good value at little over half price.
Items near Guildford in Surrey, but I can courier for additional cost (probably about £15 max).
