As to new, I would agree but with one caveat. The vast majority of new vehicles sold in the DR were not built in the US. What does that mean? Everything from component parts for motors and transmissions to tires may be of a lesser quality to meet certain price points in the countries they are shipped to.
As to used, I have always shipped my personal vehicles from the US to the DR. And it is, a royal PIA, but I know the vehicles, their history, their quality, and the hassle and expense is worth it to me.
An aside to this for those considering importing without residency, you may want to consider electric vehicles. And yes I know the issues involving electricity costs and charging and range, That having been said, the government has cut the taxes by 50% if the vehicle is all electric. In October I transferred to a buyer 9 Nissan Leafs at the port of Caucedo. That is on top of the 11 Leafs brought in June. All of those were purchased in conjunction with a tourist project in the east region..............which also carried another tax reduction.
If your travel is mostly under 100 miles in a day and you have a home charging set up............this certainly seems to now be viable in the DR...........at least for some.
