What exactly is wrong with the interior? Looks very nice and clean to me - plastics seem to be of high quality, nice satin wood trim, pretty much similar to the current M35/45 interior which is awesome. Im sure it will be available with brushed aluminum and carbon fiber trims as well, not just wood. And if the driving dynamics and performance are the same or better than the current version, and the price stays in the same bracket, then I don't see how can one justify buying a TL or 3 series over this.
