Suzuki Vitara Corrosion Protection

Hello dear community, I’m new here and would like to buy a Vitara. I read in an older article that the Vitara, which are produced for Hungary have no corrosion protection (underground wax and hollow wax) and those for DE or AT already. Is that still so? Or is it saved here too? Do the Hungarian models have nothing or are only missing the underfloor wax? And does someone know what to lay for it in a Suzuki workshop, if the later g Thank you in advance!
