Combi for the parents 17,000€

Moin moin, my parents are looking for a station wagon. Since it is more the case that I have more budget than usual, I wanted to ask forum what treasures there are for approx. 17,000€. Approx. because 15,000€ available Audi A6 should be given in payment. Wanted car: Combi color simple automatic parking aid Navi Klimmaautomaik no Franzosse rear bench has to be folded back completely. It should be traveled to the vehicle, camping. Room Hamburg To my parents: Both Over 60 years, rather quiet drivers. No way to get to work. 50% highway 50% city A6 from my point of view are too big, are more often bugged Ca. 10,000-15,000 KM a year Are not very familiar with cars or don’t want to deal with them Definitely dealers, because I can’t always be on site What I thought about, medium-sized station wagon, about 140hp petrol. Petrolers I would take because in the end quite a lot are driven in the city and then also short distances. My three I would suggest to my parents: BMW 318i Ford Focus Tournament 2.0 Volkswagen Golf Variant Comfortline 1.4 TSI I’ll leave it that way and hope that the information will be sufficient.
