1. Oil change - ditto Hazelnut, Red Hill Auto is great and you can get breakfast at the Center Harbor Diner or lunch at the Red Hill Dari while you wait

2. there's an auto detailer at the car wash in M'Borough, but don't know a thing about them.
3. you can drop off dry cleaning at the laundromat at the far end of Dunkin Donuts (they aren't a dry cleaner, they send it out like everyone else in town does)
