How many Cars can you register and then Sell in 1 year in Poland without a Dealer's license?

I have already bought and sold 4 cars this year. Each registered in my name and taxes paid of course.

how many cars can you legally buy and sell in Poland without a dealer's license? I am not making any money only having fun swapping Toys :)

I doubt there is a limit - how many TV sets can you sell (as much as you want). If there's a limit, there's something wrong with Poland ;)

As many as you want, as long as the tax is paid.

Worth bearing in mind that if you flip many cars, then they might suspect that you're dealing in cars and you'll trigger a tax inspection.
