This is a well-known and established exotic dealer in Newport Beach. I've visited their store several times and found the cars all to be absolutely impeccable and in amazing condition. Most with very low miles.
But here's a list of several cars, big, big bux with lots of bids. I mean, there is A LOT of activity on these auctions. My first thought was that they are shill bidding their cars up... but is it possible that the market is this strong for $100k plus cars?
They also have 0 feedback, which is odd.
