don't know if this has been brought up yet but in the gfx folder of the x910's data.zip there are some new .mdl files that aren't in the f one:
car_ghost.mdl
car_blaupunkt.mdl
becker_car_gps.mdl
becker_car_ghost.mdl
i dont have any 3d software to see what these models look like but might try them out when i get home. hopefully one is better than the spaceship from the f series.
