A car at Porsche Westwood? I live in ten minutes away and might be able to check the car out for cosmetics on Sunday.

A proper PPI: Try Bill at Eurotech (http://www.eurotechracecars.com/) in Framingham, or EPE (http://www.epe.com/) in Natick. Bill at Eurotech has worked on my car, and I go for track tech inspections; he is usually there seven days/week. No personal experience with EPE, but generally well regarded.
