GMC service for Waltham drivers
Waltham is approximately 22 minutes from our Stoneham shop on Pine Street. We see customers from Waltham, Belmont, Newton, Lexington, Watertown, and the wider Middlesex County area every week. Most Waltham driving runs through Main Street, Moody Street, and the Route 128 / I-95 corridor at Exit 27, which shapes the wear pattern on the vehicles we service.
Waltham has a strong life-sciences corporate base. We see a lot of company-leased BMW 3-Series and Audi A4s, and we keep VAG-COM and ISTA-equivalent diagnostic licenses current for those.
