The solution is Cardok, and is a blend of functionality and science fiction idea of the James Bond film. It is a hydraulic platform with capacity for a car interior,
which can be installed anywhere in the garden, if roomy. Can be opened with an electronic key without moving the car, so if you have to stand in the right place but instead we go down (see photo below).
As the price is around 60,000 euros. A pretty fair price taking into account the price per square meter in some cities.
