A girl friend of mine had a 535 and went to the dealer for its first 'tune-up" She called me and asked if $2200.00 was high for a tune up . After I talked her away from the dealer I looked at the cars maint. sch. for a tune up . At the mileage she had , (Iforget) The manual called so much work it was unreal. She still has the car to this day,two years later with no work other than oil/lube changes, and it runs fine. Like the afore mentioned post,fine if you can afford to maintain one.The dealer will bleed you .
