you should go find a bank loan and change it to a car loan. it's usually much cheaper to buy with a loan than pay all the lease and then pay residual. only drawback is that you gotta pay sales tax twice. you're paying for it now in your lease, when your bank or credit union buys it for you, you gotta pay tax again.
about your maintenance plan. most-likely the dealer's just trying to rip you off. if I was you, I would only do oil change, my own 27or so point inspection with fluid check, brake line check, etc. and perhaps a tire rotation if needed. don't change the mission oil as original fluid is usually good to about 30-40k miles minimum. don't get your mission oil changed at those jiffy lube places either as those places uses cheap stuff that needs to be replaced more frequently. I only believe in doing the 30K mile inspections unless there is something definitly wrong with the car.
30K inspections are usually $300 and with the parts that needs to be replaced usually goes up to about $500-600 typically at the dealer.
