Purchase advice Mazda 5

Moin, we are looking for a car for the family (2Erw + 2 children). Today we looked at this Mazda 5 at the dealer on site: I found this offer at ??????????????????: Mazda 5 2.0i Sendo, 7Sitze,SH,PDC Sendo First registration: 07/2014 Kilometer level: 120.310 km Fuel type: petrol, E10-suitable Power: 110 kW (150 hp) Price: 11.480 €https://link.mobile.de/TgmwR8HqKKMDQVKA The engine has pulled a bit, a valve (was used in other threads here times a) ls potential source of error) is still checked by the workshop and if necessary made. Otherwise we also need an AHK and winter tire (possibly as a negotiating mass). + sliding doors + 7 seats + total sufficient space + clearly below the budget of approx. 1500€ + the car dealership makes a trusting impression and is on site The impression at the test drive was fine, but did not knock us down. Is just a somewhat older and carrier car as a new for example, but for our needs with two children (3 and 9) it makes sense. I have concerns about consumption. Does someone have experience values from the practice? What else do I have to consider or should I still clarify or ask? How do you rate the price (taking into account that it is a dealer)? I would be happy about opinions or experiences 🙂 How do you rate the price?
