Let me be very specific here.
You asked about “Girls”. Now, in most cases, someone trying to date a girl probably doesn’t need a car.
If you’re trying to attract an adult woman, not having a car at all might go against you, if you happen to live in a place that requires a car for you to, say, work, or go to the grocery store, or whatever.
Where I currently live, public transportation is almost worse than nonexistent. You either own a car or you pay assloads of money to an Uber driver, or you’re stuck bumming rides from friends hither, thither, and yon.
Most people looking to begin dating someone they’ve just met do not want to become your personal taxi service, nor do they want to be the designated driver at every outing.
The type of car is mostly irrelevant.
