930 maintenance questions and gen advice sought

[Andyandyhall]

I've got a low miles 1985 930 which has been extensively restored by Francis Tuthill, predominantly body and interior but including gearbox rebuild and some minor engine work. I use it every weekend and will cover about 3000 miles annually.

I plan to send it back to Tuthill every two years for it's major service and give it an oil and filter change myself in the between years.

Do any 930 owners have any advice on this? I'm not looking to cut corners but want to keep it looked after by Tuthill (who are 200 miles from me) and feel assuming no issues come to light an oil and filter change in the between years is enough.
