Buying a car under and taxes under 44AD or 44ADA?

Hi I provide service as a network consultant for a US company. It is only a service I am offering and no goods are involved. Billing is monthly. I receive the payment into my savings bank account. Annual income would be around 30Lakhs. I have registered for GST on my personal PAN and got the Letter of Undertaking for filing GST without tax. I file the GST returns with 0 tax every month. I file persoanl IT returns under 44ADA. I am planning to buy a car and I do not want to have the vehicle under my name. So I thought of the following. Start/Register a firm. Get a PAN, GST number and current account.(The income from US would be deposited into this current account.) Buy the car under the company name. I have the following questions: Is the solution I am thinking correct? What are the tax complications? What type of firm should I start? Can I be the only owner or there has to be partners? How should I take my amount/share/salary from the firm? Do I have to maintain books for the firm? How to reduce the amount of taxes on the firm and personal? Do I have to file the IT returns under the firm? Which section to be used 44AD or 44ADA? Do I have to file the IT returns personally? Which section to be used 44AD or 44ADA? Do I have to file GST returns for both the firm and personal?
