BMW Car Wash Soap
Have any of you tried this soap to wash your car. I was at BMW today and saw this. It's a green soap that says BMW Car Shampoo costing 9 bucks. Do you think it's worth it to buy. It basically is enough for 16 uses or should I buy another brand of car wash soap to wash my car? If so, can you recommend some soaps I should buy either online or at a store like Pep Boys. Thanks.
