Try this: put your little bike or car into a container and seal it, then contact PT embassy and tell them you want to import domestic goods as you are moving to the PT. They will "help" you how to import domestic goods and your "lawnmower" duty-free. But do your own research online as well as they will not help you 100% as they are interested in charging your arm and leg if you fail to file one single form. Your "lawnmower" will be your car. You can call it a lawnmower and bring it import tax free that way. Then just keep it in your back yard as your collectible. If you have a large-enough yard you can drive it around your back yard, unregistered. Many people bring guns into the country that way as no one opens the containers to check them inside anyway. I did everything by their rules, did not bring any guns as i was uninformed, was also insulted by the embassy telling me "do not bring any drugs" since I hate drugs and druggies anyway, but I brought a lawnmower, legally and they did not charge me a penny, because it was part of the household goods. You can try to bring your small car engine-less, then "buy" a local engine, something like that may work, but otherwise just pay 10 times more for a local junk, as European cars are known for their shitty quality, even the Mercedes-Benz, and enjoy. The better solution, to save you $30K to $100K in ridiculous import fees (if you are too lazy to do your homework and bring all your stuff duty-free) is to just buy a local motor scooter or bring a bicycle of your own. Don't worry too much as they do not really give a damn over here on anything. So just relax and do what you can do. They are HAPPY that you move to their country as everyone else left to Angola, Brazil, São Tome, Cape Verde or another Third World country anyway, to get the jobs there. Local jobs pay anywhere from 300€ to 500€ a month. If you're lucky, to get a job, 5€ to 7€ an hour for temporary construction jobs. That includes electrician, plumber, bricklayer and other professional jobs, which charge 7€ to 10€ per hour. So be prepared to work for next to nothing and enjoy your relaxed lifestyle being surrounded by friendly people. Just keep in mind, the place is very safe, except that it is teeming with thieves and people that make empty promises. Always get a cash receipt on anything you pay them in cash. Very beautiful and enjoyable country and very underrated.
