I just bought an '88 780 with a 3rd gen PRV-6 on eBay, and I'm planning to pick it up on Tuesday (aprox. 4 hour drive from home). For those of you who would like to see it, here's the auction:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2433325932

I plan on driving the car home from Chicago, IL, to Holland, Michigan, and the seller has offered me the use of a covered location in which to perform an oil change and other immediate maintence before I drive the car away. As of right now, I'm planning on replacing the following items: Oil and filter change (10w30, Valvoline Durablend), Spark Plugs, Air filter, and the Differential oil if I have time.

I also plan on inspecting or filling up the following: Transmission fluid, Brake fluid, Power steering fluid, Engine coolant, and tightening the timing chain cover bolts.

Can anybody else think of anything that I should inspect or replace before driving this car home? The previous owner/driver took very good care of the interior, but she may have neglected the engine a bit (unknown history, has 144k miles). The seller received the car from her as a charitable donation and he is unfamiliar with the engine. Should I take any special tools or parts with me in case I encounter any issues? (I'll have a decent set of metric sockets and wrenches with me.)

3rd generation PRV-6 owners, your advice would be greatly appreciated.
God bless,
Fitz Fitzgerald.
