mind you, SW, that is 4 years from the first registration of the car, so if it were registered 2/1/02, then you are only covered until 2/1/06.
RX330,
However, the statement only said "Lexus" and the associated charge. Have you inquired of credit card company the specific details of the "Lexus" charge. A simple phone call will provide you with details.
