Buying a car

The question is, should we buy our son a car?  A lot of people buy their children a car when they turn sixteen or seventeen.  I have found the perfect car for him, but can’t decide.  I’ve included a picture for you and wait for your response.

Jon's car

It is a BMW after all.  It is a 1959 BMW Isetta.  It only has three wheels so he would save money on tires.  He could just stick his head out of the sun roof.  I wonder if there is still a warranty.  If it does break down, he could just carry it on a bus with him.
