MINI Service in Wilmington, MA

Factory-level MINI service for Wilmington owners. Diagnostics, scheduled maintenance, and major repair.

MINI service for Wilmington drivers

Wilmington is approximately 15 minutes from our Stoneham shop on Pine Street. We see customers from Wilmington, Tewksbury, Burlington, Reading, Andover, and the wider Middlesex County area every week. Most Wilmington driving runs through Main Street (Route 38), Lowell Street, and I-93 Exit 39, which shapes the wear pattern on the vehicles we service.

Wilmington runs a heavy mix of pickups, hybrids, and Tesla. We split between fleet-style truck service and high-voltage EV diagnostic work depending on the household.
