After a few months of looking I pulled the trigger on a 2000 996 Cab today.
I had Rudtners Racing do the PPI and was very pleased with their whole operation. I don't think they could have been more thorough going through the car and explaining everything in detail.
I left the car with them to do the IMS LNE upgrade and a couple of other more minor repairs. This will be the longest 2 days of the year, waiting to pick it up.
Thanks to all of you for the information you've contributed to this forum, it made me confident with my decision to move forward.
I'll have to get some better pics up once I get the car home.
