in summary...
335is keeps n54 biturbo setup
"regular" 335 gonna get n55 single turbo
why would anyone wanna buy the single turbo then, if they're selling both versions
I dont think this applies to SA though... from what I've heard, we're keeping the n54 until the next generation of 3 series is released (2012)
that's what they said (about fogs)
maybe they found it can be added without cutting into their margins
