Depends on availability, size of car etc . You can get an estimate from the websites of most of the major car rental companies like Avis , Hertz and such , so you would probably see anything from $120 - $200 USD for 5 days in mid November in Punta Cana.
However, from our experience with several of the car rental companies in DR ..... the estimated price you get online is often irrelevant when you get here. They will likely ask for a deposit of some amount...anything from $500 to $1,000. ....and they will draw up a new local rental contract....often with a totally diffrent price...so be ready with passport, ID credit card etc ...I’m guessing that this is because as a franchise, they can operate under local rules and procedures ...Don’t think that because you are renting with Avis for example, you will get the same prices or level of service..as Avis in the US.
And oh , God forbid that you have a minor scratch or dent when you return the car ....make sure you do a walkthrough of the car when you pick it up and take cellphone videos of the walkthrough if you can . Good luck ...and drive carefully.
