Car supermarket group Available Car is aiming for further growth after turnover reached £120m in 2012.

Sales grew by 20% and pre-tax profit rose 32% to £4.5m at the group, which has sites in Castle Donington and Sutton-in-Ashfield, according to Companies House filings.

Its directors' report said demand for used cars increased as savvy customers wanted to reduce motoring costs by replacing their older cars with younger more economical used models, creating strong demand for used diesels in particular.

The company, which has 280 staff, said it was continuing its multi-million pound investment in upgrading its dealerships.
