Word to the wise, if you are planning to rent in Jamaica. Do NOT object to a car with dents and bumps. TAKE IT! The combination of high curbs, inconsistent to terrible roads and unfamiliar driving style, i.e. British style drive on the left rules can, and probably will combine to cause at least one or two new scrapes during your time there.
Husband was trying to find a better looking car, when we went out to get ours. I took him aside and told him we should be fine with one that was already banged up. So, guess who scraped the curb? Yup. Him. AND it was on a wheel cover that had already been scraped.
Even after driving through the Blue Mountains, gorgeous but THE scariest road in condition, width and location at the edge of the mountainside, we had zero extra charges for damage to the car. An added bonus, of course, is that you look like a local as you are driving along, because everyone has dings on their cars!
