I am thinking of buying a convertible. Can you tell me which cars might be the best value for money, also considering design, price of service and repairs, etc. I would be paying under £30,000, more like £20,000 - £25,000. I would like a convertible hard top, where you just push a button and the roof rolls back automatically. Also would also like a proper back seat, like in the Ford Focus convertible. I am not sure whether to buy brand new or second hand (1 or 2 years old); any advice? This is the one and only time I will be making such a purchase and I don't want to make a mistake.
