Imperial Car Supermarkets is expanding by opening a fourth site, its first in the East Midlands.
The company already operates three sites in the South of England at Portsmouth, Southampton and Fleet.
Now it has secured a property on Bedford Road in Northampton which will open before the end of the year with up to 500 used cars in stock.
To make the process of selecting a car as simple as possible for customers, each vehicle on sale in the car dealership will come with its own online document pack. Available to download through Imperial Car Supermarkets' website, each one will contain a copy of the vehicle's registration document, service history, HPI credit check and MoT status.
Imperial Car Supermarkets also operates a nationwide price match guarantee.
The company chose the location due to its position close to the M1 motorway and A45, making it placed to serve visitors from across Northamptonshire and from towns and cities further afield such as Oxford, Coventry, Milton Keynes and Leicester.
Neil Smith, director of Imperial Car Supermarkets, said: "We're hugely excited about the prospect of opening our next branch in Northampton.
"For the past eight years we have been helping motorists across Hampshire to get the best deals on quality used cars and the team can't wait to bring customers in Northampton the same great offers.
"Work is underway to create a state-of-the-art showroom, capable of displaying hundreds of used vehicles, so customers can be assured of finding a fantastic choice of makes and models every time they visit.
"We will also have an experienced team of finance specialists on-site, ready to help customers get access to finance solutions that offer exceptional value for money and make the process of affording a used car extremely straightforward."
