Windscreen, Exhaust, etc.

I sold my 2013 135i convertible but still have the windscreen, with carrying case, and the stock exhaust that is as-new and was taken off just after I bought the car new when I had a Berk exhaust installed; it is the M Sport exhaust with Black tips. And I also have a full 32 ounce unopened bottle of 303 High Tech Fabric Guard Water Repellent: I've used this on every top of every convertible I've ever owned and found it to be the best protectant. Make me an offer I cannot refuse on any or all of these items. Thanks for looking...Bob Z.
