My friends and I want to make a music video. And for that, we need to rent a Nissan GT-R. How much do you think it would cost to rent such a car?

The price of renting any car depends on a lot of factors. Each rental service might have its own prices. You can rent a Nissan GT-R here, for example: https://getrentacar.com/en-US/car-rental/5017752 . On the site, the price is listed as almost $600 for a day's rent. That seems a bit steep to me. But the car itself is in excellent technical condition.
