Just about to order a set for my car from ebay, 40 quid, don’t know why people bother with “Genuine” ones as they’re all made the same and mine will have official logo on, in the end they’re just bits of formed rubber or plastic.
Had a set I fitted to my last car and when I did the handover the sales rep commented how they set the car off and would I leave them on the car as they were going to put it on their forecourt, still got my GCB.
