1967 Ferrari 275 GTB/4

We know from many, many years of watching classic car auctions, that there are certain qualities that ensure big money. For example, putting tiny silver horses and/or yellow badges on a red car will probably bring in a lot of cash. This is doubly true if said car hails from the 1950s or 1960s, and it's triply true if some dude drove it around in circles or if a celebrity owned it. That, friends, is how you make the serious dosh at auction.

Considering that, we should expect big, big things when this 1967 Ferrari 275 GTB/4 crosses the block at the big RM Auctions event during the festivities surrounding the 2014 Pebble Beach Concours d'Elegance.

Terrence Steven McQueen, better known as Steve McQueen and even better known as the coolest actor of the 1960s and 1970s, originally purchased this car while filming Bullitt in San Francisco, which should provide a big boost to its sale price.

As previously reported, this car has undergone a full restoration and has received its certification from the team at Ferrari Classiche. Beyond that, though, we're kind of in the dark about this beauty. We don't even have a rough guess of how much it'll go for.

That's where you come in. Considering that the price of classic Ferraris is increasing with all the regularity of Old Faithful, how much do you think McQueen's 275 will call for when it hits the stage in August? Head into Comments and let us know.
