What bidders may not realize, however, is that the exact same car sold in 2010 for $2.64 million. So that means it's being flipped four years later for more than twice as much.
Sign of a bubble? Maybe. But as long as there is a growing number of millionaires and billionaires looking for places to put their cash, and looking for long-term investments that will hold their value, cars may continue their 10-year winning streak.

McKeel Hagerty, CEO of Hagerty, said he doesn't think collectible car prices are a bubble. While values have soared in recent years, the price growth has started to slow to a more rational level, he said. Prices in both private and public sales are expected to be up a modest 4 percent this year after much stronger growth in previous years, he said.
"We are not watching a bubble, but more of an overall easing in the market," he said.
As for the Maserati that's bring flipped, he said it was a "good deal" when it sold in 2010 and has an "impeccable history."
"While some headlines might suggest a frenzied market, this is continually evolving into a more calculated and rational market with the strongest demand on the more discriminating cars (like the Maserati offered this weekend)," he said. "We don't expect too many surprises this weekend."
