Converting a hardtop into a convertible is like transsexuality. After the change, it is no different from the eunuch, which belongs to grandstanding. If it can be seen after modification, the price is generally twice the price of the car, and the body needs to be re-welded and reshaped, similar to scrapping and reloading. This kind of car is a tool, and changing it into a convertible is nothing more than an act of coercion. No matter how rich people are, they won't have hundreds of thousands of convertible cars. Wouldn't it be better to buy a convertible Porsche directly?
