Control chain at Alfa Romeo Brera

Hello, I looked at an Alfa Romeo Brera today. But the dealer didn’t mean the sale in Germany because he is already 11 years old and you have to change the tax chain after 10 years. Supposedly the chains tear at the Brera after 10 years because something went wrong. That is supposed to be uneconomical in Germany. Is that true or has he exaggerated that? Did you exchange your tax chains? If so, what did that cost? VG Chris
