Luxury car ownership involves a lot of depreciation and the Aston Martin DB11 is no different. Since the V8 model is less expensive at the beginning, it may have a different depreciation curve than the V12 model. Maintenance costs, fuel efficiency and market demand factor into how well these cars retain their value over time. There are arguments to be made that the V8’s lower entry price and potentially lower running costs could make it more attractive in the used market, but the V12’s exclusivity and traditional Aston Martin character could help it retain value better over the long term.
