tanelvali, good for you for joining the DL club. I really doubt the owner would care that you are admiring their car. They parked it on the street, surely they would know that it would catch some eyes. If they saw you and were true car enthusiasts, they would have a smile on there face, and wouldn't mind talking to you about the car if they happened to walk up.
Great shots. Not many people go as far as to get the Pininfarina badge. Looks like you and your lady really got a kick out of seeing the car. Good stuff
