This is the Secretary Problem.
If the second car is a Volvo do I pick it, or hold out waiting for a Mercedes? If I pick that Mercedes, am I going to regret it in thirty seconds when a Rolls rolls past? Am I going to get stuck with an old Hyundai due to my inability to settle?
The solution wouldn't be to still skip 1/e if you got something like googol - 1 on the first try.
