I don't know, for me this video only exposes some of the M235i weaknesses. It puts a lot of distance between M235i and true M cars, highlights how not-special-at-all the n55 is (unfortunately) and further elevates the legendary status of the e46 M3. The n55 as beautiful as it sounds and performs, is no match for BMW inline 6's of yesteryear.
I could listen to that e46 M3 sound track all day long.
And I do agree, an 8 speed auto would probably best the M3 CSL time. But the e46 would probably leave you with better memories and more endorphins.
