Residual value calculation by the manufacturer bank in case of financing

I ask the question separately here, because otherwise it is probably going down: residual value calculation by the manufacturer bank for financing: How realistic is this information – is the residual value rather poorly calculated or yet close to reality??? Example VW Passat List price with special equipment: approx. 53.000 € Price after special discount incl. transfer costs: approx. 40,000 € Credit interest: approx. 1.600 € Costs Total: approx. 41.600 € Rest value of the bank with financing with 1.99% over 48 months with Fahrle is this a realistic invoice or too pessimistic and I could expect a higher resale value (at least the offers are never so cheap with the portals with similar age+running performance)? Are value loss models of a well-equipped used one really cheaper, because also wear and possibly repairs come in Thank you very much! Franz
