Price BMW I8

Hello people, who knows about it and can contribute constructive messages? Why does the bmw I8 keep so good in price? Sometimes seriously admission numbers are as low as never before and from the beginning stood firm the I8 is actually not worth its money. Processing in the interior and a real athlete it is not. Technical innovations I see compared to Tesla at the I8 also not so please how do the prices come to such prices? Currently cheaper at mobile.de 89,000€ mi t 120,000km running ?! Who buys such garbage ? Have already driven the I8 itself, of course the part Mega and for all BMW fanboys a must! But well for the money ?!
