We see such TV commercials during every holiday season -- a huge ribbon on the top of a fancy new car parked on the drive-way, and a loved one instantly becoming so elated. Sweet. However, every time I see such a commercial, I always wonder if it is even possible to buy someone a car without him or her knowing. Every car must be registered and insured so the owner of the car must sign a few documents before you drive it out of the dealership, right? Can buying someone a car as a surprise gift be really possible?
