Well some cars break with tradition when it comes to depreciation. From what I have seen the Aston Vantage V8 is holding its own, despite AM in general having horrendous depreciation. The V8 is a desirable car and that keeps its value high.
The old Maserati coupes just didn't have the goods. Not the looks, not quite the performance. So they depreciate. This one is a bargain. Ferrari engine, great looks, a great interior. This is a much better car than a CL. It has some soul. So I am thinking it won't tank in value as quickly.
Still, we'll see how it is after I test drive. I have a whole new perspective on what I like/don't like after driving around a supercharged NSX.
