60/60. I guessed on two though. Aston Martin DBS vs. Vantage; I can't really tell the difference between new Astons.
Cadillac Deville vs. Eldorado: Only got it because I remembered the Eldorado name was introduced some time in the 50s, and the car in the picture had a split windshield.

Oh, and the Hyundai Pony. 'Pony' makes me think of the older style RWD versions, so I wouldn't have picked that... Except it said 'Pony' on the side.
