I am not impressed with anything from BMW these days in terms of looks. Fantastic engines but boring looking.
It looked like the trunk is better designed. The older versions had a trunk that just looked awkward to me.
I am sticking with my CTS Coupe any day of the week compared to a BMW.
Diff design language...the design language of today's BMW is just toned down Bangle--or smoothing it out. In terms of the M5, all M5s have the "wolf in sheep's clothing" look. Including the E60 M5...the reason it was more extroverted, was because the E60 5 series was more extroverted, a departure from the classy E39 5 series, which still is my favorite.
The CTS coupe looks good from the front, but awkward from the side and 3 quarter view---it's that C pillar and hatchback look...it's BMW counterpart, shows how to style a 4 place lux coupe...it is effing blazing...
Now, I am by no means a BMW fanboi, because I am really feeling the E Class coupe, I don't think Mercedes has a AMG variant planned, but if they do, it would be a beast.
Lexus needs to get on the ball. They are slowly offering more engine and body choices, but they need a IS coupe (instead of the IS hardtop convert) and a GS coupe, and a true SL and CL competitor...
Caddy is apparently working on a SL and CL competitor---but that is a rumor, they've had a clay model of a Bentley Continental Coupe competitor, it's called the ULS or ULC (ultra luxury Sedan/ ultra luxury Coupe)
