Is the smart a disposable product?

Estimated smart drivers With the high fuel prices, I am also thinking about whether I should switch to a more economical car. My American already consumes a lot. If I look at Americans at Autoscout, then most have 150’000, some 200’000 and other 300’000 kilometers on the hump. Quite different with the SMARTs! There are hardly any of the more than 120’000 made! Is the SMART a throwaway product that you throw away with 100’000km?
