If you are really worried about this car deal tell her you are CHOOSING to not have a car .....
Give her some BS about how f*ckin green you are and your carbon footprint and global warming and all.....
Gives you lots of BS to talk to her about....(study a little about it first)
Makes you look principled, like you have a belief system, confidence, a sense of mission and self.....
You're a stand up guy who doesn't care how others live and what they think.....
This also explains why you don't have what you (really) think is one of the basic things a man should have....a f*ckin car
OR.......
If it's that important .....
Spend some time getting your life, self, mission, confidence, together .....get a decient job, your own apt, and ....a car
Either way will work....
Move on from there.....
Only as important as YOU make it ......
Over and Out.
