Have you a car Is it correct sentence?

Answer 1

"Have you a car?" is a technically correct sentence, but, at least in the United States, it is not idiomatic and will sound strange to most listeners. The idiomatic version is, "Do you have a car?". Simple present and past tenses are almost never used in the USA. for questions. Instead, the intensive tense, formed by the appropriate tense of "do" plus the infinitive of the principal verb (without the word "to") is used; the question begins with the appropriate form of "do"; that is immediately followed by the subject, which in turn is followed by the infinitive of the principal verb.

For perfect tenses and for the passive voice, no additional word is added to the verb form, which already has at least two words, but the same "inverted" effect is obtained by placing the auxiliary verb before the subject, followed by the remainder of the verb.
