MX5 keep a life long and drive as a vintage car

Have such a small dream. In the next one or two years I would like to add a new/almost new MX5 as a pure summer car, keep it up to the oldtimer and beyond. However, I have the fear that a new car can no longer become so old. For pure durability reasons it should become the big engine 😉 To an Asian manufacturer I would be most likely to build such a durable vehicle today. One would probably have to expect one or two replacement motors per decade (sorry I can’t stop now) What do you think about it?
