Expats have had a good experience using Compramos O Seu Carro. Additionally, you can consider listing your car on local platforms like OLX and Standvirtual, which are popular in Portugal for used car sales. When selling a car here, remember that you’ll need to complete the transfer of ownership (registo de propriedade) through IMT services, and it’s a good idea to have the car’s documentation, inspection, and tax records up to date for a smooth transaction.
