There is a guy with a national reputation for his knowledge of Boxsters in Florida who is very wired into the scene and who has a business which, among other things, does an excellent PPI. He does everything from preparing a racing Boxster to producing products for Boxsters to conducting tech training sessions at national Boxster get-togethers.
Pedros PPIs
I highly recommend him based on reports from people who have used him. He is very well known on
PPBB , another Boxster forum.
Get in touch, let him know what you are looking for and then use him for the PPI. He may know of a car that is just right. The site has a picture of his forms so you can see the type of inspections he does.
