Not a Thai thing at all but seems to be global.
Why is it that car manufactures insist on calling their products 3 or 5 door models when it is obvious they are 2 or 4 door.

Just who gets in and out of their car by the hactchback (the 3rd or 5th door ) ????

In the general run of thing I would guess very few and then it would not be the norm.
