Missing service booklet of a 1993 964 Speedster

Hi guys,

I've bought one of my dream cars, a 964 Speedster. Unfortunately the service booklet is missing... The car was originally sold in the USA and I believe somehow one should be able to get some service history out of the Porsche dealer computer-systems. Over here in Switzerland, the official Porsche importer would very likely have some records and could probably tell me which of its dealers has sold this one in 1993. Do you know if it is the same in the USA and what I would have to do to get as much of the car's history as possible? Thanks a lot for your help.

Cheers,
Mike

Would be great if you could point me in the right direction how to get some (hopefully) stored maintenance records from Porsche North America. I guess they keep the data for (at least) a certain time-frame. This Speedster has been in the USA until 2014. I've got the Carfax yesterday but only renewal of title and number of owners mentioned.

Thanks, input is greatly appreciated.

bump, thanks for your ideas
