Renting a car

Hello. Is this ABC car rental company? My name is Jason and I want to rent a car from your company. I need a car that can seat up to four people. Do you know which one is good? Also, I need a car with an automatic transmission. The brand is not an issue as long as it's big enough because I will bring lots of luggage. Do you have one available for next weekend? I need to use it for three days. Finally, what will it cost? Do you calculate it based on a daily fee or the model of the car? And how can I pay for it? Can I pay by credit card? Is there anything else I need to know? Thank you.

-> Finally, how much will it cost?

-> And How can I pay for it? (Don't start with a conjunction.)

-> Finally, what will it cost? Do you calculate it based on a daily fee or the model of the car? And how can I pay for it? Can I pay by credit card? Is there anything else I need to know?

Just a suggestion: (You said "Finally", but there are 4 more questions that followed your question about the cost. I think it would be better if you organize it or combine some of your questions like so: "I would also like to know how much it will cost me. Do you charge based on daily use or the model of the car? Finally, can I pay for it by credit card? If there's anything else I should know, please do inform me. Thank you) - in this case, there are only 2 questions instead of 4, and you can use "finally" on your last question.

I hope this helps.
