Higher age or more kilometers?

Hello, have planned for a combo purchase 6,000 – 7,000,- EUR. It should ideally run for the next 4-5 years without going into extreme rep-costs at a mileage of about 30T per year. If I’m now looking for a passat, but only models that have already been on the hump for 10 years, if the kms should not be significantly above 80-90 T… I don’t know much myself and therefore need your expert advice. are ten years too old today for a VW that should hold a few more years without costing me a reperature capacity? What can you typically expect from upcoming repertures? I am very indecisive..even Variant or Octavia are actually in question, but a pass would be nice…what would you do? Or does it make sense to take a slightly younger one who ran a few kilometers more, because he doesn’t have to be afraid of 200Tkm. in the bucket? Thanks already for any support! Greeting cue
