My brother is a used car dealer in Cotui. You may call him at 809-240-0909. Just ask for Johnny. He should be able to give you prices and models.
When it comes to cars in the DR, I would say never buy brand new and always buy Japanese made cars. In my opinion the best types of cars to own in the DR are the Honda CRV, the Toyota RAV4 or something like that. I personally prefer the CRV. The reasons are:
- Too many potholes and bumps, so you need something with more clearance than a normal car can provide.
- Gas is expensive as compared to the US, so you don't want a gas guzzler. These vehicles have pretty good mileage.
-They give you almost as much room/space as a full sized SUV without all the expenses and hassle.
-They are Japanese. Very important in the DR, because for one thing their quality tends to be much better than American and European cars. In addition you can find spare parts and people to service them anywhere in the DR. Not so with American made cars.
