I am looking for a 320D and was quite interested in those offered in BMW Premium Selection. The new F30 is out of my budget. I have a few questions on buying from Premium Selection:1. Warranty - It says 5 years warranty, but is it from the date the car is registered or from the day I purchase it? I was told that for Pre-owned units, some only has 3 years warranty?2. For 3 years warranty units - It also say that its either 3 years or 60,000 mileage. So if the car has clocked 40,000 mileage, does it mean it only has another 20,000kms more before the warranty void? Or its 60,000km mileage on top of the already clocked mileage when I purchase the car?3. What does Free Servicing cover? 4. Are the price quoted in Premium Selection negotiable?5. The price quoted by Premium Selection is higher. Is it worth paying for the warranty? Alternatively, I can go for slightly older 320D that may not have warranty and save myself 30-40k. Surely nothing major repairs that would cost me up to 30k in the next 3 years right?Thanks in advance for your advice
