Please regard that the comparison table is missing, but I'll give you a general idea. First, the comparison must be made according to the following aspects: cost, utility, model, and convenience of the car. In the same way, it is necessary to know if you are buying a used or a new one from the dealer. According to this, the utility of the Volkswagen depends on the type of model, and its final use. If someone were going to buy a family car, the Volkswagen would offer more space, a better design, a good speed and more convenient price than a mini cooper. If instead, the person seeks to buy the car just for him and to travel, maybe the Cooper is more convenient for its speed, but it is usually a more expensive car even without taking into account the model and year of manufacture. So that, the Jetta has the advantage of size, price, utility, and warranty, that although the Cooper also meets the last two, its high price and size would not work for a family car.
