You can have it permanently. However, legally speaking, you can only drive it for six months in a calendar year. This means the six months need not be continuous and also means every 1^st of January the term starts automatically from zero.

Now, let us come to real life. Given the fact that EU citizens no longer have to have their car formally sealed, there is no effective method for the authorities to prove whether or not you are driving the car and for how long.
