Leasing used Cooper SE useful (Mini next with booking)

Hello together, I’m thinking about completing a private lease for a used Mini Cooper SE. EZ 04/2021 KM: Good 30t full equipment, costs at 42months and 5,000km close to 250€/month. It really requires so few KM, because second car and relatively short working distance. My questions: 1. Is this due to the age and the KM associated with greater risks from your point of view? At Abhabe the battery will be 7 years old. 2. Mini-next for 320€ for the first two years of meaning additionally to book or is there too much “excluded” anyway? Thank you
