Excuse me, I couldn't help but notice the sentence "Does she have a car is correct?" It seems a bit odd to me. Are you asking if the statement "She has a car" is grammatically correct, or are you wondering if it's factually true about a specific person? If it's the former, I'd like to clarify that the sentence should actually be phrased as a question, such as "Does she have a car?" without the additional "is correct" part. If I've misunderstood your intention, please feel free to elaborate further.
