Is a car with low depreciation always a good lease deal?

Not always. Low depreciation helps with the residual side of the lease equation, but the money factor (interest rate) and selling price also matter. A vehicle can have excellent residuals but still be a poor lease deal if the dealer refuses to negotiate on price or if the manufacturer sets a high money factor for that month. That said, strong residuals give you a structural advantage that is harder to overcome than a high sticker price. In general, low-depreciation vehicles offer better lease value on average, but you still need to verify the full deal before signing.
