Call a shipper before going any further. It's hard to find accurate information online about the costs and procedure, plus it's not always updated in a timely fashion. I shipped a car over a couple years ago with this company: https://www.a1autotransport.com/ship-car-to-costa-rica.php and I'd recommend them to others as well. What I would not recommend is going off of information you've found in an online forum. Talk to a shipper that delivers in the area, or contact the federal agency in charge of importing vehicles if you want the low down.
