 Despite accounting for 50% of all UK bus sales in February 1989, sales slowed and in 1990 in an attempt to shift stock, Volvo had Plaxton body forty chassis.Twenty-five of these bodies were the only Plaxton 321 bodies built, this being the Plaxton derivative of the Duple 320 body acquired when Duple closed.Volvo acknowledged that the Tiger and B10M were broadly similar, and whereas Leyland had sold 3,500 Tigers since the model's launch, Volvo had sold 20,000 B10Ms during the same period.
