It has been used to get a few free cars. When the 50 Years of Porsche was introduced, you could enter a code for a free Carrera RS 2.7 (1972) which costs R$300,000. There has been at least one more code but I don't recall what for.

Do a search. The codes may still work. Beware though, several of the cars in "Porsche: 50 Years of the 911" are gold cars, so be careful unlocking new tiers.
