Good experience ordering parts for '81 Mercedes and '95 BMW. Excellent quality and perfect fit and good prices and the choice of several manufacturers. All orders have come on time and exactly as ordered.
Until Oct 2018 when somehow the service rep could not understand they had sent the wrong part and so even after a detailed message explaining the problem no resolution. After 30 orders over 3 years I known what part I ordered. A 1 star review this time.
