I get cheaper auction fees with being in the trade better selection of cars from main dealer. Only advice I could give is to avoid cars that are privately owned and entered at all cost
Yep, buy cars that are described as being "direct" from either main dealers or fleet operators. Do your homework first because you'd be surprised at the prices asked and the buyers fee. you can often do better in a private sale as long as you know how to weed out sellers who aren't genuine private sellers.
