Its too bad you don't have a friend thats a mechanic. I agree with the previous posts...expect to pay for repairs....and be blessed if you don't! I think 100.00 a month/1200.00 yr for repair items is really an underestimate.
Fuel pump, AC, water pump, any engine things...your call. My experience is expect to pay. My car had huge bills between 75-150k,.... but I really love my MBZ
