Secondhand purchase 2004 Honda Jazz CVT – Questions

Hello, I’m interested in a used Honda Jazz 1.4 CVT year 2004. with 68,000 km I’ve come across the following familiar problems myself: – e.g. the CVT/Rubbel/Drivingrubbing – AGR/Exhaust recirculation valve known problems – water in the footroom at the back or in the suitcase area because roof seams to the trunk partly leak Are there other frequently occurring abnormalities? How does this model look like with the service intervals? Is there a maintenance plan in the net somewhere where you can see what needs to be done when? When often? For example, every 10,000 km or 12 months How expensive? Transmission (CVT) Oil replacement intervals? I have read: The first time at 80.000 km or 5 years later every 4 years Is that true? Are there tooth belt replacement intervals with the vehicle model? Set valves? Generally, where have a focus on it? Geared (CVT) Oil – Here I have read the initially factory-side a non-standing oil was used. However, this was not done by a return call?
