Mr Jones said the award is based on sales across the 2015 year and the trophy was awarded at a Suzuki dealers' conference last month.
"We sold 135 Suzuki passenger cars in that year. The Vitara and Swift were the high achievers for us."
He said the industry was enjoying a buoyant phase at the moment but the award was something special for the dealership.
"This year we're tracking much the same as last year so that's very pleasing."
He puts the success down to two things - great staff and a product to match.
"We've got a great team here and we all get on really well. We pride ourselves on that," Mr Jones said.
