Kelvin said: "I really enjoy my job driving around the SA postal code area and driving the 'Merc' makes it extra special."
Celtic Couriers general manager Gareth Jenkins said he was delighted at the addition of the Mercedes sprinter to the company's fleet.
"Reliability is all important to us here at Celtic Couriers. Adding new vehicles to the fleet is very important. Meanwhile, we also take great care to ensure that all our current delivery and collection vehicles are up to scratch.
"It's all about being about to deliver the goods here at Celtic Couriers and making sure that our fleet is as up-to-date and as well-maintained as possible is very important to us."
