Mileage Millionaires Can Bid for a Ferrari Factory Tour

Ever wonder what the biggest spenders, mileage-wise, do with their million-mile stashes?

Here's one option: a trip to Ferrari's headquarters and factory in Maranello, Italy.

That's one high-end award currently up for bid on

United's MileagePlus award-auction site

.

Here's what the winning bidder will get:

• Two roundtrip business-class tickets to Milan
• Four nights' hotel accommodations in Italy (two in Milan, two in Maranello)
• Rental car
• Guided tours of the Ferrari and Maserati headquarters
• Driving simulator experience
• Visit to the Ferrari Museum
• Dinner for two at Cavallino Restaurant
  
  
  
  There are now 23 MileagePlus members bidding on the trip, with a current high bid of 605,000 miles. But with almost nine days remaining in the auction, it's a safe bet that the most serious bidders will wait until nearer to the end and bid the price up closer to a million miles.
  
  That's a lot of tickets. And no, the prize does not include a Ferrari.
  
  The auction ends on January 8, 2014.
