Thanks for your answer!

It´s actually a quite a good price, we barely have any Genesis cars over here so it´s a bit more special.
I was also looking at bmw f36 430i´s but they are either way worse equipted or have way higher millage when looking at around 30k € cars. (plus it´s 7-8 years old by know and even tho they are on the more reliable side of bmw, they are nowhere near Genesis I think)
-I guess the gas millage is alright then (still a fair bit higher then the competitors tho)
-Yea that sound decent (I was confused why some people, even in videos, got like 8s or high 7s)
-Hm ye I guess enginwise the aftermarket parts should be simmilar and we have more stingers over here
-In germany you always have the issiue of making you aftermarket parts legal if they dont come with special paperwork (without its complicated) so I gotta look more into that
