Vertu Motors is set to open a Fiat brand centre in Newcastle.
It will represent the Fiat, Alfa Romeo and Jeep franchises and will operate from a leasehold property which Vertu signed in July.
The business is expected to commence trading in August 2014.
That expansion will be quickly followed by a further development in Newcastle, when Vertu launches its first dealership with the Japanese premium brand Infiniti in September.
Vertu said this dealership is located 10 miles from the Nissan factory in Sunderland where the Infiniti Q30 model range is to be manufactured, and the centre will be the sole Infiniti sales outlet in the North East of England.
