7 seats car / 7 seat car

[phoenixqn81]

Dear teachers,

As knowledge I've learned, I will say "7 seat car", but when surfing internet, I see many websites write "7 seats car"; "7 seat car", and also " 7 seater car".

Are all they ok and can I use all these ways?

Thank you in advance.

"7 seats car" is wrong in standard English.
"7 seater car" is also not common, but "The car is a 7 seater" is OK. (That is, '7-seater' as a noun.)

(You'll see all sorts of nonsense surfing the internet. Don't believe it all.)

Thank you much. And so I should use "7 seat car".
By the way, I would like to ask you this:

50 meters high
50 meters in height
50 meter height

3 above ways are all ok, aren't they?

Yes.

50 meters high
50 meters in height
50 meter height

3 above ways are all ok, aren't they?

With the right words before and after those phrases, you could get all of them to work.
Would you like to try them in sentences?
