Went past Booran Holden last night to have a look - they've got some Omega's and SV6's on the front lot - the sporty models definately look better - the Omega's look kind of "sparse". I never actually noticed in the pics what little front overhang they have - the front wheels are basically in the corners!!! They look good from most angles, the only thing that I didnt completely like is the view from directly front on - the flared wheel arches look good from any other angle, but from front on they look huge!
The other thing that made an impression on me was that VT-VZ was good at hiding how big a Commo actually is. The VE though IMHO looks big.
