RRG sold 3,500 new Toyota and 600 Lexus cars last year, more than any other group representing the twinned marques. Its six Toyota outlets in the North-west account for 4% of new Toyotas sold in the UK. RRG has four Peugeot dealerships in the region.
The group has opened three new dealerships - for Lexus in Manchester and Bolton, and Peugeot in Manchester.
Chairman Michael Smyth said: “In the last three months we have completed a £5m investment programme in anticipation of future volume increases. We are forging close partnerships with manufacturers.
“Provided the product is right, there will always be a place for good quality dealerships.”
