Nice finds for sure. Good to find vintage at carboots, does happen sometimes! I know what you mean about aggressive people. Carboots near me are bad for people wanting games, lego etc.
Day off today, went to a carboot near me. Managed to find this Rancor monster for £5. I was paying the seller for something else, just saw this in the bottom of a box, under some books. Pleased to find it out and about!
