Largely, women that are into cars are going to be nearly impossible to impress, OR just want their shit worked on for free. Cars are a dope hobby and even more so a fun one to share with others, but I don't know that it's ever going to be the root of picking up a woman.
My wife was casually into cars, but I don't know I'd say
into cars. These days with how talented she is, she's not gonna be impressed with somebody with a clapped out mk4 (though I'm glad
@sterkrazzy isn't coming to CSB meet, she's a big Audi fan

)
Idk, it's a broad stroke to paint the whole population with, but I'd say it's exceedingly rare. I've seen a number of people who try to use others' hobbies for personal gain and have no interest in making a personal connection, and that's a shame. But it's a good thing to keep an eye out for.
