Understanding of financing (residual debt)

Hello guys, my question is almost a bit unpleasant to me and I’ve already gone so much after that but I just can’t find the answer to my question. I hope you can help me? Briefly to my situation. I’ve been self-employed for 2 years and my 20-year-old Omega has died. Has simply done its services. Now I’m probably the classic financing or leasing case, because I need my money to increase my company and invest further. I would like to finance or lease a cheap small car (I don’t need the car for representative purposes or the like). For this I played a bit around in the Sixt configurator and the following understanding question: e.g. Citroen C1, list price 11.740€ (just for all gross) With 10% deposit, 24months and 15tsd Km/year a Finaz.rate of 110€ As far as so good. Now what I don’t understand: 24*110€= 2640€ + 1.174€ from the deposit = 3.814€ which I almost paid to the bank until expiry Now I read only what of “the borrower can take over the Fzg at the end of the term to residual value or –EINFACH BACKED–” The Fzg has a residual value according to Sixt of 5.440€. My invoice looks like this: Debt to Bank 11.74€ after 24 months – 3.814 = 7.926€ Remaining debt to Bank If I give the Fzg “back” I return to the bank a current value of 5.440€ (residual value, assuming there are no additional costs) Is in my view I owe the bank Then there are 7,926-5,440=2,486€ of which I don’t read anything about it anywhere?!? If I’m wrong, I just have to give the car back? Sixt has a final payment (with the details in the configurator). But that’s only 350€ in this case. What do they mean at all? If one calculates these, one lies in the sum of the costs if one leases the Fzg. If my ignorance excuses, maybe I also make a mistake of thinking. until now I was in the happy position n Is this type of financing really a Sixt-characteristic? Call this Vario-Financing. Or is this model also available at the dealer on site? Thank you very much!!
