Update: The results are in, and it seems there are some sellers feeling let down. Only one car managed to hit its pre-auction estimate. Three cars remained unsold. We've updated the list to reflect the final sale prices.

Monterey Car Week operates in a realm distinct from the typical automotive market. In this world, selling a car for a million dollars is considered a bargain. Several high-profile auctions are happening this week in central California, and we've reviewed them all to spotlight the top contenders. This year, seven vehicles are expected to break into the eight-figure range. Ferrari is heavily represented, but an old competitor might snatch the title for the most expensive sale. Final prices could exceed $20 million, a staggering sum even for the elite.

Here's a snapshot of the $10 million club for Monterey Car Week 2024, based on estimates. We'll provide final bid prices once the excitement subsides.
