At McMahon, we pride ourselves on having the most transparent certified pre-owned sales process in the business. We don’t use hired wholesale buyers who don't care about the vehicles they purchase. Instead, we select our own pre-owned vehicles, ensuring we only bring quality vehicles into our inventory. The result? A vehicle purchasing experience you can trust.

Peace Of Mind


Every pre-owned vehicle is personally selected by P.J. McMahon himself, ensuring its quality. McMahon Relationship Managers are not paid to obtain pre-owned cars. We take no incentive for putting an undesirable vehicle in our inventory.

When you purchase a pre-owned vehicle from McMahon, “Certified” isn’t just a hollow buzzword. It’s a personal promise, from our family to you.
