When I sold my Tiger at auction last year, the costs were basically:
- $700 entry fee,
- 6% commission for unreserved, 8% for reserved
- buyer pays 10% on top of sale price.
On top of that I paid $600 to ship the car to the auction, and because I am in Canada and shipped my car into the U.S. there is a 2 1/2% duty charge on appraised value (even though the cars was going back to the U.S. where it originated) and charge for customs clearance paperwork.
It certainly adds up, so when you see a Tiger sell for $80,000, you're not getting that. At the same time, it really isn't easy for a dealer to make money after bidding for the car, add 10% buyer's premium, ship it, possibly fix any flaws that may or may not be obvious, finance it, advertise it, and then sell it for more. Then, if and when a car is sold, Uncle Sam will take a good chunk of the profit.
