Why, what do we have here?
1. Cars, you get a test drive. Girls... no such luck.
2. 10,000 miles doesn't seem like much on a used car... yet, on a girl...
3. With a used car it's probably a good thing to ask the previous owner about the mileage... not so much on a girl.
4. Girls have better, um... ‘glove compartment's.
5. You never really get a true sense of why you're the one getting either. If they're both so damn great, why would they have been given up in the first place?
6. It doesn't really matter if girls are ‘winter driven'... you still just prefer that they were new.
7. You can check under a car's hood. Of course, it'd be cool if you could do that with girls, but it's just not the case.
8. Girls don't belch smoke out of their hind end... usually.
9. Cars. Fill em up with gas. Buy insurance. Oil, other fluids, tune ups, tire rotations, etc, ad nauseum. Girls... well, girls are still higher maintenance.
10. Cars have stereos. You may only get am, or you may have to smack the speaker on the drivers side all the time, but cars have stereos.
11. You truly know when something's wrong with your car. It'll come off with some wicked clunking or rumbling or the whole car just fucking dies on the road. Girls? Heh, not quite. You can ask and ask and still get ‘nothing' when you ask ‘what's wrong?'
12. There's someone who can fix what's wrong with your car, a mechanic. Or the retailer, or something. Try bringing a girl back to where you got her and saying, "I'm getting this odd teeth grinding noise..." and see how far you get.
