Hello, Since I have to get new generation a combo, and I have decided for a Volvo V60. I have now tested 2 pieces, an Ocean Race and an R-Design, both unfortunately with automatic. I really liked the dynamics of the R-Design now, and I am about to configure one. But I still need some help from the Volvo veterans. Volvo V60 D4 R-Design with manual switching -Saphir Black -Leather Anthrazit -Motion Pack (RTI, parking aid front and rear, 7 inch Navi & High Performance Sound) -Winter Pack (Adaptive Xenon Light,heitzte Frontsitze) -Electrically fold-in exterior mirror -Darked rear and side discs -Rain sensor -Dachreling Anthrazit What’s the difference between high performance sound and premium sound? Is high performance ‘good enough’ if you like to listen to music? Do the built-in child stiz booster on the ruecksitzen something?
