Hi All, I picked up a 1991 560 SEC, 77000 miles, last week. The car has been maintained very well, with very low miles driven in the last 15 years, but I think certain items are more time sensitive? Foe example, all the belts were replaces 12000 miles ago but that was in 1998!

What maintenance items would you recommend that get addressed? The car runs beautifully, but I was thinking of the following, so please add where necessary.

Oil and Filter
Differential oil
Replace all drive belts
Check all cooling hoses
Transmission service - car shifts beautifully.
AC recharge

Anything else I should look at - car was stored indoors in a climate control garage and so is well preserved. Thanks for the help.
