Twenty years in, we're still the same family-owned garage — just with a bigger team and a lot more experience.
Guaranteed Auto Repair started with a simple frustration: too many Windsor drivers were paying for repairs they didn't need, or leaving a shop more confused than when they arrived. We opened with the opposite approach — show the customer what's actually wrong, explain it clearly, and only fix what needs fixing.
That approach is still how we run the shop today. We're independently owned, which means no corporate sales quotas and no pressure to hit a monthly upsell target — just a team of technicians who'd rather earn a repeat customer than a one-time invoice.
Guaranteed Auto Repair opens on Wyandotte Street with two service bays and one rule: never recommend a repair we wouldn't approve for our own family.
Word of mouth from honest repairs fills the schedule. We add a third bay and bring on our first full-time apprentice technician.
We invest in dealer-grade scan tools and alignment equipment, so newer vehicles get the same honest, accurate service as the classics.
Four certified technicians, a service advisor, and a shop still owned and run day-to-day by the same family that opened it.
Certified, experienced, and all local to Windsor and Essex County.
Sets the standard for every repair that leaves the shop — still on the floor most days.
Oversees every job for quality before a vehicle goes back to its owner.
ASE-certified, specializing in engine and computer diagnostics.
Your first call — walks you through findings and pricing in plain language.
We sponsor local youth sports teams, offer discounted safety inspections for first responders, and hire apprentices out of the local trades programs — because a shop is only as good as the community it serves.
