Refer to your car by its brand name in a sentence to a woman you've just met.
Example: "The lexus is only parked a block away."
Other Example: "It looks like it might rain. I hope I didn't leave the top down on the porsche."
Here's the thing, a girl isn't going to be impressed by a car if the owner seems equally impressed by it. It means the owner has bought something he can't really afford. Which is stupid. And very unimpressive.
Exception: "Can I give you a ride home in the Hovercraft?"
Other exception: "I need to get the tank back to the military base before someone notices it's missing."
