Open to Everyone
You Don't Have to Buy From Us to Service With Us
At Marden Motors, we have a fully licensed auto shop, and offer fast, friendly service to everyone — not just those who bought vehicles from us. We perform comprehensive auto maintenance services and repairs, all completed to the same high standards as our vehicle refurbishments.
Our experienced mechanics can handle any job. We perform thorough engine diagnostics for every issue, and will give you a prioritized list of recommendations. We communicate fully with you, so you know exactly what we've identified and why any work is recommended or necessary. No surprises, ever.
We're proud to be serving Guelph, Ontario and are committed to becoming your auto shop of choice. Before starting work, we will provide you with a complete estimate for all work, carefully review all details with you, and get your approval. There are never any hidden costs or unapproved work.

The Marden Standard
Our Reconditioning Promise
Before any vehicle earns a spot on our lot, it goes through our reconditioning process. That means mechanical issues are addressed, the interior is cleaned and detailed, and the exterior is inspected for anything that needs attention.
We believe in presenting every vehicle at its best — not because it looks better in photos, but because you deserve to see exactly what you're buying. No surprises after you drive off the lot.
If there's something we can't fix to the standard we'd expect, we simply don't sell it here. It's a simple policy, and it's served us — and our customers — well for over 45 years.
