Chairman Graham Knight says the company will build on Culver's reputation in the North-west. “Culver's name will be retained. Its Toyota franchises will continue to remain distinct from our Smith Knight Fay operations, though it will function under the Smith Knight Fay group umbrella."
The deal involves Culvers' dealerships in Stockport and Macclesfield.
Smith Knight Fay, which last year turned over £131m, has moved its Knightsbridge Mazda franchise from the centre of Stockport to an eight-acre development at Green Lane, adjacent to Junction 1 of the M60.
The company has already completed a major facelift of its flagship Volkswagen Centre at the site and moved its Stockport Lexus dealership to a £1m facility.
When the Knightsbridge Mazda operation opens in July, the development will be the North-west's largest car sales 'multiplex'.
Mr. Knightsaid: "Our plan is to focus several key dealerships in one central location, rather like an out-of-town shopping mall.
"If offers customers maximum choice and concentrates technical expertise to guarantee the very highest standards of care in every way.
"Car dealers must learn the lessons of other retailers and provide the widest choice of brands and services possible, at centres that offer easy access for customers."
