How important is Money/whips(cars) to college girls?

Let's say the guy is cute/good looking and 18(non jailbait)...drives a 2010 porsche cayman but is occasionally caught rolling around in his dad's ferrari 458 italia...if you're with him you seriously DONT have to worry about money for the rest of your life...he's not a snob but a smooth talker...downside is he smokes an 1/8 of weed a day but doesnt drink and "get down" with the frat boyz..lol
