    This seller provided a great ebay experience. There was no need for communication as his description and pictures were clear and concise. After I won the bid and made payment, he quickly processed my order and got my purchase on its way. It was tracked and arrived on time to me here in Hawaii without any damage. He packed my items well and individually wrapped each item. I highly recommend this seller and I will be checking in on his available items often as I will definitely buy from him again

    Once again, David's Supercar Parts is a winner! Shipped quickly and arrived well packed and in fine shape. Reasonable shipping cost. Just as listed, described and pictured, perhaps in better than expected condition. Virtually ready to install, it's that clean! Good communications too, if necessary, and knows his stuff, too! A fine transaction with a great eBayer... Thanks Dave!
