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.
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?
