The golf is definitely not the car to impress most women but that is a dumb reason to buy a car. But one you like and enjoy driving and be confident in it that is more impressive. Plus any women who likes you for your car probably shallow and that doesn't sound like someone you would like.
I guess I also want it to be a bit of a status symbol as well notwithstanding trying to impress a girl. I know the golf is going to drive really well and also quick around the corners. Audi is a 4WD and chassis is bigger and bulkier, so it'll be slower for sure but potentially more 'menacing'?
But anyway, of those 2 cars, if you see me driving, which one would look more impressive?
