Well, my dad seems to think he needs more cars so, he bought 2 additional Porsche's to add to the 4 he has already.  I'm sure everyone's itchin to make a ****ty comment but, he worked all his life and made himself what he is today so, **** it he likes cars.
 
 
1969 Porsche 912 Targa soft window.  The soft window is very rare and will only increase in value.  His is British racing green which I find kind of funny.  The shop I work at is repainting the car to the factory shade of green.  It's a very clean car and only has 55K original miles and is 1 owner.
It looks identical to this:
 
 
1996 Porsche 993 Turbo.  A sought after car as it's the last of the air cooled 911.  IMO, the best looking 911 ever.  Very clean, rare color, low mileage (9K), 1 owner car that will also increase in value.  See a theme now?
 
  
 
 
 
What a great day he must have had. 
 
 
he will also be adding these to the collection.
 
 
To answer the inevitable question, he's a petroleum engineer.
