Down here in Puerto Rico 3's are popular in the 2.0 car version but we don't have a lot of 3's HB.
Anyways I'm going to start doing that to check the people reaction.

 

3 reasons I don't.

1) as much as I love Mazdas, I own an Rx-7, not a 3, and most modern day Mazda Owners (even Rx-8 owners) have no clue what my car is, due to one single mazda badge on the rear of the car (or if they can read my center caps, as Mazda had no logo yet in 87, just the stylized Mazda text)

2) I see Mazda 3s ALL THE TIME. I don't know what you guys are talking about when you say rare, but if I honked at all the 3s I saw, I'd honk maybe 4 times a day.

and

3)I don't honk often, even when I see other Rx-7s (that actually are rare), I raise and lower my headlights as kind of a car wave instead.

 

eh i see a TON of mazda's in tucson the only thing i do is wave to fellow 8 owners.

 

i let my blow off valve send a small whistle out .. like a construction worker whistling at a hottie passin by
