Yep. That's the place. It's actually the only shop I know of in the area that can give you a notorized calibration result sheet. It's right across from the Red Lobsters on Lee Highway (Rt 29) in Fairfax.

They put the car on a roller, check the calibration, and write it on a sheet (actual vs readout). The paper is notorized, and it's legit in court. Oh, and M&M Collision only takes cash. It's $50, flat fee.
