Had a Jet Black/Coral Red 335xi coupe for almost 3 years, traded for Jerez Black/Fox Red. I love this combination. It was just enough of a change-up from what I had with the 335. I think any kind of Red Leather is pretty rare outside of higher end luxury cars, so it definitely makes it stand out a bit. I saw a Black/Black M3 about a week ago in my work parking lot, and that combo came across as stark and a bit depressing to me.
