Blue smoke is a sign of burning engine oil, in my opinion it sounds as though you have a bad seal around your valve stems (i.e. bad valve guides) and oil is slowly working it's way down the valves and into the combustion chamber. This would explain the blue smoke and the difficulty in starting the car after it's been sitting for a day or more. Is this a high mileage car, the reason I ask is because the car is so new, it would seem odd to have bad valve guides this early in the game.
