Used Audi A7 lease, meaningful??

Hello, I intend to lease a used Audi A7. The monthly leasing costs of a new A7 for a value of 48000 € (discount included and no deposit) cost about 700 €- 800 €. What would it look like if I leased a used A7 for a value of 40 000 € for 36 months with 10000 km of driving performance per year? Would it mean that the leasing costs would be considerably lower than a new vehicle in the month? Of course, I don’t expect exact figures, but I wouldn’t expect to see a new car. I’m glad if someone could tell me about what you can get for a used A7 monthly. Greetings Azami
