Vinny, I don't think they usually like it when you refer to them as 'hoes'. Also, don't worry about your car. I drive a BMW. I get compliments, but I don't get chicks cause of it. In addition, it's cliche, but confidence is the key here. Just don't worry about it. For some reason girls dig guys that couldn't give a shit about them. I'm not saying ignore them, but just realize/act like you don't need them. Talk to them while realizing that it doesn't matter if you look stupid. So what if you strike out with a few? There are three billion women on this planet. If one doesn't want you, then you don't want her.
Oh, and as everyone said...cut down on the weed. It's probably making you too laid back.
Also,
"The Ladder Theory" might help you to understand a little better about how men and women relate.
