A new Mitsubishi dealership due to open in Norwich later this month will become the twelfth dealer to join the franchise since the start of the year.

Constitution Motors will open its doors with Mitsubishi at its long-standing dealership in Constitution Hill on August 26.

The family-run business, established in 1958, is teaming up with Mitsubishi Motors in the UK as the brand undergoes huge growth with registrations up 32% on a strong performance in 2013.

Managing director of Constitution Motors Ian Coates, who took over in 2002, said: "We run our business based on great customer service and pride ourselves on our high levels of customer retention – which we know is central to the Mitsubishi brand."

The dealership, which employs 22 people, including Coates’s wife Sue who runs the aftersales department, and their daughter Emily, a service adviser, will undergo a refurbishment in the coming months. It has had an on-going relationship with Norwich City FC for more than 10 years and has previously been an official vehicle supplier to the Carrow Road club.

Lance Bradley, managing director of Mitsubishi Motors in the UK, said: "We are delighted to welcome Constitution Motors to the Mitsubishi family. The dealership is a well-established and respected family business whose core values reflect our own perfectly, and I wish them every success as they join us at a very exciting time."
