Yup, when I was breaking my Zed I had soooo many folk wanting these little pieces of plastic it was unreal!
£5 each is a joke also.....i ended up giving the ones I had away.
If you live near White City, Car Giant has 2 Z4's for sale, well they did last weekend....maybe you could pay them a visit...not condoning theft at all tho.....merely permanently borrowing them!
