New member with 1986.5 928 in garage, help with history

hello all,
Back in July I purchased a 86.5 928 & I've been enjoying bringing the car up to roadworthy status. Which means that I've not been driving it near as much as i'd like to.
some spec's- 91,000 miles, 5-speed, Prussian Blue with tan interior, generally in good shape but has sat for a while.

I'm reaching out & asking for any help in discovering her past life since she came with no records. I've attached a compilation of date, mileage & location info from Carfax, Autocheck & InstaVin. If anyone knows of this car & could help I'd greatly appreciate any information, service records, old photos, stories, etc. I'm sure its even possible that the Owners Manual & service book are in some box awaiting to see the light of day.

Thanks for any assistance & please email with any info or questions.
David

Welcome, David. Are you aware of the 928 Registry?

Yes, I've edited the cars registry entry & it "needs approval". There was no prior owners or specific info previously entered.
I've perused the registry & its interesting. I like the car count net to the options list. I sure there's a lot more to discover.
Thanks
