Berlingo automatic purchase advice

Hello, I’m looking for a suitable Berlingo to be able to spend the night in the car on the go, to be flexible for performances with the band in the surrounding area. Due to my age, my knees and joints are strained. That’s why automatic and cruise as purchase criteria condition, have two models to visit in the next few days. Both times it is dealers and it’s about 2015 multispace from 1st hand: 135,000 km, new Tüv, Panodach for 11700, – 280000 running Km, 01/25 Tüv, abnbr.AHK for 6500,- (No dealer warranty…) Could I “risk” the many running because “air” for repairs. What are the problems with many kilometers, can a long-distance driver (1st hand, highway…) have been? Does the resale value play a role? What should I pay attention to anyway, which questions (to the model Berlingo) in general? Thanks for answers, opinions and tips and greetings from the Allgäu
