Peter Dunnion established Dunnions Whitehouse Motor Services in Ballybofey in 1968. At that time, this was one of the largest garages in Donegal. Peter built his reputation on selling quality vehicles and throughout the years paid particular attention to providing a first class aftersales service for his customers.

Having gone on to become one of the most well known dealers in the motor industry in the North West, he continues to be on site daily, using his 45 years of experience to ensure high standards are maintained. In 2011, the business moved to its new location, adjacent to the old site (now LIDL in Ballybofey).
