Hi there, and welcome to the forum.
Are you talking about a specific car or about cars in general?

Welcome to the forum. :hi:

Do you have a question for us about those four sentences?
What age group are your English students? What English-teaching qualification do you hold?

 

[Skrej]

While none of those sentences are grammatically correct, none of them are idioms, either. What is your idiom-related question?

The car is economical.

Which one is the best?

They all sound like good cars to me.

Which one is the best?

They don't mean the same thing. Which one you use depends on what you want to say.

Abuarab, you clicked "Like" and "Thank" on all the posts that those questions came from but you haven't answered any of them. Are you still interested in this thread?
