What is the car for, a DD, an investment, a prop?
Are you worried about all costs or just the purchase cost?
Sounds like you need to think this through a lot more. If you only need a car to drive for a short time and want to save money you should get a used car and if saving money is really important than you should probably buy a modest, used Honda that will likely be very low in maintenance, gas and insurance.
