Regular timing belt change – expected costs?

Hello municipality, my beloved C70 D3 (150 hp) is now 10 years old and according to the maintenance plan, the timing belt change is within the scope of “however” maintenance. Can someone give me a house number in Euro, which awaits me if I have this done at my Volvo contract workshop? I am just thinking about whether I can delay the change for another year, because I actually imagine that I have been careful with the engine. (no speed orgies, just relaxed weeks) dfahren – running performance at the moment 108 TKM ) On the other hand, I know that material fatigue is quite normal. I would rule out arguments like “reselling value” – the car is written off for me and I just keep driving it. I just wanted to hear your opinion whether the 10 years are rather overcautious, or whether you should give it to the car. Greetings, Cesevenzig
