Has anyone developed a theory about why

1) 90% of the used car in Dubai has been driven by a Lady, and why this should be a good sign, since most women never opened the hood to check engine fluid levels in their own whole life.

2) most of the used car in Dubai are "very clean" as their only characteristic sign in the posted ad, enough to warrant this adjective the title of the ad, as if to buy a clean car would represent more value than to buy one with half mileage on the clock, etc.
