For alignment, I've been happy with Dornicks in Madison on Main St. 973-822-0488
For overall Benz, fellow by the name of Imre (Imree) in Short Hills. Independent Car Service is the official name, but he usually answers the phone with his name. Don't let the short hills address fool you. Prices are good. 973-376-2623 is his #. He's right across from the Short Hills NJ transit station, so it's nice for pick ups and drop offs.
Imre may do alignment, but I needed tires as well, so did both at Dornicks.
Straight shooters, both of them.
