ive got a pug 406 and added an airbag to mine you can do the same thing as me as i know it works with all peugots simple go to tesco get a carrier bag (no holes) blow air into the bag put an elastic band around the top to stop air escaping and hang it from you rear view mirror you can also add airbags for rear seats but this involves getting the 10p bags from tesco so it does depend on your budget
