Car Found

My investigator came through. I have the Pininfarina Spider's current owner's name, address, and telephone number. The car is only a few miles from the house I grew up in. Now I need to get the huevos to pick up the phone and call the guy.

How exactly do you start a conversation like this?

Me: Hey, I hired a guy to track you down because I want to buy your car.
Him: You what? What kind of person does that?
Me: No really! Tell me, how is the car?

Me: Hello? Hello?

I'm looking for suggestions, people. HELP!
