To highlight a positive example. We are now in the second year and have used the special repayment in full twice. And if it were allowed, we would have repaid even more. It depends on the attitude. I'd rather make a special repayment than buy a new car even though the old one isn't broken yet. I estimate the OP similarly. It is similar with my sister and also with some acquaintances. I am really surprised that so many people apparently do not take advantage of the special repayments. In the circle of friends and family, the attitude is different. But I guess it also depends on what parents instilled in you.
