I don’t know that about Arnold Shark is the biggest dealer in the UK and practically got a dealership on every Street Corner lol i was in Linwood retail park yesterday and there must be about a dozen dealerships there ( sadly all owned by Arnold Clark ) there is no harm trying as many dealers as you have the energy to, but like Byrdo says any good deals are far and few between
you’d think with it having loads of dealerships they’d fix the potholes in the retail park lol
