Purchase advice comfortable family carriage

Hello. I’m thinking about buying a comfortable, large family combi for the daily 2x45km to work as well as extensive holiday trips. (total about 30tkm/year) Budget would be 1000€ – preferably more 5000 direct and the rest as reserve for repairs. It is absolutely never driven sporty and should be so quiet, comfortable and optical/haptic pleasant. After a short research the C5 Tourer as diesel seems to be the optimal vehicle for this. The engine should v I think one of the 2.0s would be a good compromise. According to the fuel monitor, similar consumption values should be achieved, as with the 1.6s. I still have a few questions: Do I recognize the hydropneumatic damping in ads probably at the control unit behind the switch lever or? Are there any indications, what one can recognize, whether a massage seat is installed? Was there actually only for the driver or also for passengers? Is there otherwise still too Considerable comfort details (special equipment), which I don’t know yet, but which make driving even more pleasant? Is always the same kind of Klimatronic installed? Is Xenon/Led in the C5 very good or no big gain compared to the normal light? If an interesting car shows up, then it is the optimal procedure to book an appointment at the next Citroen workshop for a thorough check-up at the same time at the test drive date or you can also book the special problem zones yourself. call and have the rest done at the Dekra – used car check o.Ä.? Many thanks and greetings Tunfaire
