The reason why the F15 doesn't look as sporty as the E70 in these photos is the due to the wheels/option differences. Once you see the F15 with the Msport 20"s and its a whole different ballgame. Even the current E70 looks hideous to me unless it has the 20" wheels and fender flares.
Edit - Optional 20"s with the Msport package with fender flares
