We rent from Island Cruiser Jamaica. The rental is negotiable as to what the prices are. The cars are based on a Toyota Tercel so it's reliable and good on gas. From Negril to YS Falls and back was about 1/4 tank, roughly about 8 dollars usd. Roads are semi clearly marked, then again, there's only really 2 routes to Negril, one goes through Sav the other goes by the seaside.
It's easy to navigate the roads, no need for satnav. Most roads are not marked on the GPS anyway.
We usually rent 2 or 3 cruisers at a time, and (ours is the one in back), the roof comes off for the entire trip.
