The renders looks spot on in terms of current design language and the M3/4. Not sure how I take the news on the I4 layout but I guess as long as the power is there and its a true M above the M235i below the M4 then all good.
Renders look fantastic by the way, perfect!
///M4 Built on its way to blighty now!
