In Russia the average car is 10,4 years.
If you’d deduct millions of the 1980 Lada Rivas which refuse to die and cost nothing to run, the average age is going to be probably half that of the US.
Of course the number of automobiles per capita in Russia is well under half that of the United States.
But at least that sentence passes for colloquial, American, English. Unlike some of the machine generated translations your Russian Troll farm has been posting lately.
Except, of course, for "10,4" English speaking countries use a period, not a comma, to designate the decimal, so you should have posted "10.4" if you want to continue the lie that "NorseViking" is an American Expatriate living in Russia, and not just an account at a Russian Troll farm. Whatever happened to the guy who posted as NorseViking a year ago? He never would have made such a simple error.
