I have a friend with a 2015 Aston Martin Vanquish Carbon Black Special Edition. Beautiful car. In very good condition. And he doesn't drive it very much as it's a weekend only car. Maybe I should wait for him to get a new weekend car and offer to acquire his. The 2015 Vantage V8 GT is another great car to get. And they seem to depreciate fairly slowly after the first two years; they're now holding around 70% of their original value and depreciating extremely slowly.
Another idea would be to just get a new Lamborghini Huracan, the depreciation is relatively quite slow, especially if you get the RWD version. It's easy to drive, it's reliable. If you look at a 2010 Lamborghini Gallardo, today, now after 10 years of age, the car is still nearly 50% of its original value! So from a depreciation perspective, these Lamborghini cars cost less than leasing a new Mercedes S500!
