Car undercarriage retract

The new retractable undercarriage feature of the Blund 3 liter sports is a development of the adjustable hydro-pnumatic suspension systems availible for some years. When the car is parked up and the breaks set the suspension can be set to the full retract possition. The wheels retract upwards untill two specially placed skids on the underside of the car come into contact with the ground taking it's weight, the wheels then fold up and into the wheel arches as they continue up leaving contact with the ground. Once fully retracted slatted metal flaps (like the door on a bread bin) slide over the wheel openings closing them off. Not only is the car much more secure from theft as not only has the ignition to be forced but the wheels have to be unlocked too before the vehicle can be stolen, the wheels are protected from vandals, and the car is much less likely to run away if parked on a steep hill, breaks can fail, but if it's sitting on it's belly it CAN'T roll off.
