Just got my 2019 certified beginning of this year. Will probably keep it until 2028, then maybe sell it to upgrade. But by then the s750 might be coming out so maybe i'll wait it out.
I just hope with all these technological advances added that they learn to make it realible and cost effective so that every hard working citizen can afford one. While I see the trend moving towards a European look, not that it looks bad but I prefer the current s550 and s197 in terms of looks...
