Dropdown menu buttons

Hello Sir,

This is a wonderful plugin. I have a few questikons. Could you please let me know how to handle those issues?

Can we make a drop down list of all the makers?
Could we make a list of all the models in a drop down box. If yes, can select makers first then add a model name thus create a list of models depdning on makers? If we select Toyota, all the models added under Toyota maker should show up
Can we make other drop dons such as Fuel Types like Gasoline/Diesel so that, the admin can select a type instead of typing it every time he or she is uploading a car

How can we add few more boxes or delete some of them depdning on specific requirements of our own?

Sorry to harass you with so many questions.

Thanks and best Regards
