The Boston Sportscar Company 596 boston post road Weston, Mass 02493 Tel: 781-647-7300 Website: www.bostonsportscar.com I sent my car there for diagnosis. They said they would charge me $ 500 for round trip towing and diagnosis. After I placed the order, they sent their own plat back tow truck came over Albany, NY picked up my car on the next day. They actaully let me know that what exactly was wrong on the next day, and I decided to let them fix the car. Therefore, they didn't charge me $ 500 for towing and diagnosis. One good thing is that they towed my car back to me after the car was fixed without paying a penny. Moreover, the mechanic took some pictures on the engine in order to show me the damaged part on the engine and sent the pictures thru e-mail. All in all, they are very efficient and I satisfied their work!
