What should be preference on buying a car?

Other answer:

Anil Chandran:
The first requirement is that the model you choose suits your lifestyle. What do you need the car to do for you? Then you need to have a price range. Then you test drive cars to try and find faults. See the link for wise guidance.
I am the preference of buy car
The best car YOU can afford. After that whatever your preferences are ie your needs and wants (fuel mileage, space, optional equipment, traction options, power options etc).
Love big words:
Paying cash
Focus on the things you need, not what you want. For example, if you don't need an SUV, don't get one, sedans are cheaper and more efficient.
