The Lutterworth-based company’s additions are all TGX 26.440 tractors with XLX cabs and 12.4-litre six-cylinder engines, delivering 440bhp at 1,800 rpm.
Owner Harry Moran was taken to the Munich factory by MAN to see one of his new vehicles rolling off the line.
The company has 220 trucks and 330 trailers, and is a long-term MAN customer.
A spokesman said: “We have tried different models in the past and we are impressed with what MAN has to offer. The whole package is attractive and there is a strong dealer network, too.
“We have purchased 50 TGX 26.440 tractor units this year and we are gradually putting them in to service at our operating depots in Reading, Oswestry, Lockerbie, Manchester, Leeds, Lutterworth and Rugby.
“We will be looking to add another 80 vehicles in 2016 to complement the current fleet.
“MAN met the benchmark and that is why it won the tender. It has proved itself and delivered against expectations.”
All the vehicles are supplied with a two-year repair and maintenance contract.
