Well, I wouldn't say it QUITE like that!
It doesn't take money to please all girls. However, if your money or YOUR CAR are what your girl was first attracted to then your relationship is likely a lost cause over the long run.
No, for this type of girl it won't matter how good looking OR how rich you are. There will always be somebody better looking or with a faster car that she'll run to if that's the case.
Fortunately (I've heard) they aren't ALL like this!
Now, what was the topic again? I forget.
