nice render looks cool but i can't see it looking like that.
Front end- headlights look crazy off, i hate the 6 series headlight look, i can't see signs of led's from spy shots. but i hope the design is close.
Rear- diffuser is way to big, even if you say mtech bumper can be way different, the spyshot shows tow hitch way low so no. backend overall is way too high.
just my opinion
