This is the Amstad Arvana 4 door saloon.

It has no windscreen pillar so you got an almost 360° panoramic view. I personally like that and the rear lights arrangement.

It features all the things the vanilla car had which is replaced except dials and seatbelts.

Interior is from Rockstar (original fugitive customized), I don't do interiors.

how to install:
Use OpenIV Tool and replace fugitive here:
