are you sure that they are all the 6 spd? they are probably a little more popular now but before each dealer was only getting 2 or 3 a month. FYI: to be the 6spd, the V6 emblem will have red lettering as well as the 17 inch wheels.
another reason for a lot of accords is the fact you are in ohio. im in ohio as well and the accord is made in marysville, ohio. that shouldnt effect the amount of accords that each dealer would get around here, but the period of time it takes for the dealers to get the cars is a lot less. just an idea...but i honestly have no idea why you seem to be seeing so many. possibly just b/c its a good car.
