I can go all scientific on this but I'll just be quick with it.
Things like cars are resources, not only does a great car make you look cool but it definitly increases your value, or DHV as some might say. It is hardwired into the brains of women that they look for men that provide resources and having a nice car sure helps. Unlike men that want women for their youth and good looks, women look for a man that can provide resources while she takes care of the children.
This is why smart and/or athletic men are such a turn on; they have the capability to provide resources.
Now, you might be thinking 'haha no way man, they don't want children, they want the car' true, but false. The concious mind doesn't but the unconcious does. Same question is like, why do men want sex that often? It's hardwired

To make a long story small: shiny cars definitly are a turn on. And to answer your question, yes it is DHV.

p.s. Post in the right section, this clearly isn't a routine. Mod, move please.

While you are right in your premise. It is very easy to fake such a thing or even pretend you have resources. Its not very hard to get a used BMW that is in good condition and not very old. I saw a good condition 2007 530i for sale at a Honda dealership for $26k. Seeing that most girls barely know anything about cars they most probably won't really know the car is 3 years old. All they would know is its a relatively newish car that looks expensive. Your premise also ignores how easy it is to make girls think you have money when in reality you don't.

And what do you think PU is based on? DHV stories, good posture etc etc. Creating that high value for yourself that gives you the possibility to game high value girls. Having money is just as strong as pretending to have money. Girls can't see your bank account when they meet you, they can only assume you have money or any kind of status, what eventually gets them attracted. All these aspects reflect to either having resources, pretending you do or having the possibility to get them.
