The 22,000 number...
@645,000 Elantras sold 2011-2013 in the US
Idaho has one half of one percent of the US population
So that is @32,500 2011-2013 Elantras sold in Idaho.
They came in ten colors, one being white. Say white was average
@3,250 2011-2013 white Elantras sold in Idaho
Even if they don't get totalled, a low $$ figure bar as that car ages, the lifespan of Elantras is on average 10 years/$150k. (doesn't pay to put a new engine/tranny in) So....maybe half of them should be off the road by now.
Even conservatively, that is like 2,000.
