I agree with the above. But you can also do well buying at an auction. It kind of depends who's running the auction (what company), the marketing and especially what type of audience there is at that specific auction. What bothers me is that the auction company here takes an additional 10% premium from the buyer and probably also 10% from the seller. So if you can agree privately it will benefit both parties, IMO. Wonder what the selling price would have been in a private sale!
