Why don't you give him that 930 you have in your stable
My first son, I gave him a nice 77 320I BMW, it didn't last the week. Then he totaled a nice 84 F250 diesel truck, of course only liability ins, ouch.
Next was a Subaru, that one last almost 6 months, I was done, he was now on his own with a replaced car and ins. Next was a VW Quattro wagon, nice car but for the next 2 yrs, it made it in the repair shop every 6 months for some body damage. My Mother gave him the grandma car, a buick century which got totaled 6 months later.
My next child was my daughter who got a VW jetta and drove it until the wheels fell off it. My last son got a Subaru which he drove till he went off to college which until last yr went free of even getting stopped.
The first kid no concept of what was right, second one getting better and by the third one, he signed a agreement on driving infractions he might incure, the way to go.
