[200q20v] 90k service

[Mark Trank]

Can any listers advise as to what maintenance services they have done at the
90k mileage interval?  I'm at that point (actually, 2k over it) and,
according to the AOA-recommended schedule, the following should be done:

replace: engine oil/filter, air cleaner/filter, spark plugs, brake fluids.
check:  V-belt tension and condition, adjust as needed; transmission,
brakes, drive shaft boots, front axle dust seals on ball joints, tie rods
ends and tie rods; battery electrolyte level; coolant and washer levels;
on-board diagnosis system fault memory and purge if necessary.

Timing belt was done at 60k; no need to do it at 90k, right?

Spark plugs--replace at 30 or 60k intervals?

Other than the above, this list looks pretty reasonable.  Any thoughts or
suggestions?  Many thanks,

Mark
