Young used ones comparatively expensive?

Hello together, because of interest I was interested in the ca prices of young used Smart – and find this expensive! My current Coupe is a 451 84ps Passion from 2013. Very good equipment with not all but many extras (list new price were about 18,000eur). Purchased at Mercedes, was at that time just over 3 years approved, 33tkm driven and cost 7800eur incl 1 year warranty. I would see the 453 90ps twinamic as the corresponding successor from the current series. W If I’m looking for cars from 2015-2016 with 25-40tkm, the offers are from 8800-12000eur. Apart from Coupe and Automatik, there are not even further restrictions (equipment). Even if I got my 451 cheaply, and in 2016 also the 453 was already on the market, I find the quoted prices already expensive, even inflation adjusted. I would be interested whether you share the impression or how you feel about it?
