The distinction nobody makes
Two different things get called “a 4x4” here, and only one of them usually matters.
Ground clearance is the height of the car above the road. It is what saves you on a rutted track, a steep concrete driveway, a speed bump built by an enthusiast, or a puddle that turns out to be a hole. Most of the time, this is the thing you actually need.
Four wheel drive is power to all four wheels. It is what saves you in mud, loose gravel on a slope, and water. You need it far less often, but when you need it there is no substitute.
A high-clearance two wheel drive SUV covers most of Guanacaste life. Full four wheel drive is for people who live up a hill on an unpaved road, or who spend the green season exploring.
Where a normal car is fine
The paved network on this coast is better than its reputation. Liberia airport to Coco, Ocotal and Playa Hermosa is paved the whole way. So is the road to Tamarindo, the road inland to Sardinal and Filadelfia, and the highway network generally. If your life is town, beach, supermarket and airport, an ordinary car does it.
Where it stops being fine
The moment you leave the paved routes. Hillside neighbourhoods above Ocotal and Coco have steep access roads, some concrete, some not. Playa Grande, Ostional, and most of the beaches worth the drive are reached on gravel. Rental houses at the end of a track are common, and the track is the thing to inspect, not the house.
Then there is the green season. The same road is a different road in October. Ruts deepen, surfaces wash out, and fords that were dry in March have water in them. This is the reason the checklist says to drive the road to any house you are considering, ideally when it is wet.
What to do about it
Rent before you buy, and rent the ordinary car first. Two or three weeks of your actual life here tells you whether you ever wanted the clearance. People who buy a serious 4x4 in month one often discover they drive to the same four places every week on tarmac.
If you are buying, remember that import duty makes vehicles the line item that blindsides Americans. A used 4x4 here costs considerably more than the same vehicle at home, which is another argument for finding out what you need before you commit.
