It's not the matter of if the car will be cheaper here, it's how much are you looking for a peace of mind. If you are the original owner and if the car is reliable, I'll say bring it in even it'll cost you couple of thousands extra. If you like to try your luck playing Russian Roulette Dominican Style, where no bullet were removed, be my guest. All the used car sold here are cleaner then new but when you dig in you will not like what you'll find. I've looked at 6 cars through carfax and every single one had the odometer turn back at least 50k miles, some had accidents and some had multiple visit to dealer before it was sold. I end up buying almost brand new Kia through another Korean family departing and I paid more then what I would pay in US for a used car, but still it was a killer deal.
New = you can buy it here.
Used = DO NOT BUY IT HERE.
