This might be too easy, but after the last two stumpers you guys need a softball tossed at you. Go ahead, smack it hard!
Four are easy. There are SIX cars visible though, which might up the difficulty quite a bit.
And here I thought I knew all the cars visible… there are actually SEVEN!
If you look closely at the “embiggen’ed” photo above you will note a sliver of car between the Corvette and Cayman. The reverse angle shot (see my last comment below for the URL) ID’s it as one of a Ferrari’s “sedan/coupe” type cars from the 70s.
