@littlemouse The opposite direction, about 1/4 to 1/2 mile apart.
So no chance they collided and one kept driving for a while?
Nope, no chance at all.
@waterboy, they were completely different makes, models and years of cars. So not a dealership. Even if it was a common mechanic, the odds of both happening at the same time and place (roughly) must be pretty darn high.
