Our spare wheel was stolen from the rear of the car in the time it took to go inside a toys r us and buy a buggy. Apparently its very easy to steal and can come off in a few minutes. Just thought i would warn other Xsara Picasso owners. Apparently a lock can be put on to deter thieves. Of course i could also warn mumsnetters to be careful in the toys r us car park in purley, as thieves are operating in the area :-(
