By the way, the Volvo service tech at the dealer suggests this stuff as his "recommended maintenance"
                      (for the low low cost of $550 USD)
 

• Check and adjust shift linkage
• check and adjust parking brake
• check lights
• check horn
• check and adjust wipers and washers
• replace breather & clean niple (nat/aspirated)
• check for fluid leaks
• check for tranny leaks
• check & adjust clutch (N/A for auto, obviously)
• inspect tires
• set tire pressures
• rotate if necessary
• inspect brake pads
• change oil & filter
• inspect fuel and brake lines for damage & leaks
• inspect drive shaft joints for play
• check rear suspension for wear
• inspect body for corrosion
• clean & fill battery
• check and adjust drive belt
• replace spark plugs
• replace air filter
• replace pollen filter (if equipped)
• replace oil filler cap seal
• change coolant
• replace fuel filter and seal
• replace distributor cap
• replace ignition rotor
• flush brake fluid
• perform throttle housing service (cleaning & gasket, I guess)
• lube doors & hinges
• check & top off all fluids
• clean & lube power antenna (not on wagon)
• reset service reminder
• road test

                      I would imagine that I could do about 95% of this stuff and just have them do the belts. It can't be that
                      hard to inspect for rust!
