Used car sales of Lincoln Welcome to Ian Shammon Ian Shammon, who runs the Boultham Park Garage with his son Steven, has been selling cars in Lincoln since 1963. This is a family business where the accent is firmly on selling good quality late cars, serviced and valeted to a high standard. We run a highly successful operation that has stood the test of time because we offer a highly personal service. Many customers return time after time for their next vehicle. It all began when Ian Shammon started working in car sales for Campions, then the Rootes Group in Lincoln, in 1963. Six years later he went into business on his own as West Parade Car Sales, where he remained until moving to his present site at Boultham Park Garage in 1979, when he was joined by his son Steven.
