Ok, besides the steering wheel, and the seats/radio, what is different. I can't pin-point it... dash? Center console? When I look at a pic of mine, vs a S4 car, I don't see a difference... but there is one right?

 

lots of little diffs...

radio surround. vents. round gauges. 6.5" door speakers.

 

the center console is a lot more solid on the s5's as well... logicon's diff too

 

do you know if i can use a s4 steering wheel on a s5 vert?

The vert has an airbag, the other doesn't.

 

Yeah, lots of little differences. Like mainly the mouse belts and all the trim associated with it that has not been mentioned.

 

Don't forget the shift ****!
