NEED HELP ANSWERING A CAR RIDDLE??

Question

Someone gave me this riddle, does anyone know the answer... I don't think it is really about a part of a car i think you need to think outside the box... Not like seats, or doors.. here is the riddle..

SOME CARS HAVE ONE,

SOME CARS HAVE TWO,

NO CARS HAVE THREE,

SOME CARS HAVE FOUR

thanks

Answer 1

SOME CARS HAVE ONE, Seater

SOME CARS HAVE TWO, Seater

NO CARS HAVE THREE, Seater

SOME CARS HAVE FOUR Seater!!!.

Answer 2

I thought outside the box, but led me nowhere,

but inside the box,.... I see

that this riddle is talking about something not really noticeable except when you are behind any car which is 'TAILPIPES'.

Some Cars have one tailpipe like most usual cars

Some Cars have two tailpipes like some of VW new beetle cars

Some Cars have four tailpipes like BMW X5 and BMW M5

BUT No Cars have three tailpipes and if there are then they are almost rare.

Answer 3

People.Or animals and pets.

Answer 4

its talking about seaters

Answer 5

For those that say Seater, have you heard of McLaren F1?

It's a 3 seaters supercar.  As it is also street legal, that should count, as a car right?  So, "some cars do have three seaters"

So, seater is not it.
