Meet the Founders of GCM Sourcing
Share
At GCM Sourcing, we believe buying a vehicle should be centred around the buyer, not the seller.
That's exactly why founders Reuben McCartney and Brandon Buckley created GCM Sourcing—to offer a completely different way of buying a car. Rather than trying to sell what's already on a forecourt, we source the right vehicle for each individual customer based on their lifestyle, budget and requirements.
Whether you're looking for your next family car, a prestige vehicle, an electric vehicle or a commercial van, our goal is simple: find the best vehicle available anywhere in the UK.
Reuben McCartney
Co-Founder | Vehicle Sourcing Specialist
Growing up within the motor trade, Reuben has developed a genuine passion for helping people find the right vehicle.
He manages the sourcing process from the very first conversation through to vehicle handover, ensuring every customer receives a transparent, personal service.
Rather than recommending what's easiest to sell, Reuben spends time understanding exactly what each customer is looking for before searching trusted dealer networks and trade-only platforms across the UK.
His focus is on delivering exceptional customer service and making the vehicle buying experience simple, enjoyable and completely stress-free.
Brandon Buckley
Co-Founder | Vehicle Inspection & Technical Specialist
Brandon brings the technical expertise that gives GCM Sourcing its confidence.
With years of hands-on experience working on vehicles, he understands what makes a quality used vehicle beneath the surface—not just how it looks on the outside.
His mechanical knowledge helps identify reliable vehicles, recognise common model-specific issues and ensure every sourced vehicle meets the high standards we expect before recommending it to a customer.
This technical approach allows our customers to buy with confidence and peace of mind.
Why We Started GCM Sourcing
We founded GCM Sourcing because we saw too many people settling for vehicles that simply happened to be available.
We wanted to build a business where the customer comes first.
Instead of asking "What can we sell you?", we ask "What vehicle is right for you?"
Every recommendation is based on your individual needs—not sales targets.
