Will most likely work out some thing like this :

Car - €22,000
Ship - €1,000 (no idea of cost from SA to here)
Import duty - €2,300
VAT @ 23% - €5,819
Customs fee - €250

Cost of car excluding VRT - €31,369

There will be other costs like having a vehicle inspection done, NCT, bloody good clean as they get filthy from being on the boats.
