I went through the same question and debate a few years ago.
The vote swung in favour of the Calais V due to the following:
- Prussian Steel body color (love it to bits)
- 19" Calais V wheels (SSV style, but lighter grey on the wheel barrel)
- HUD
- Perforated, flat bottom steering wheel (with no blank switches, due to below items)
- Collission avoidance and lane keep assist
- auto tilting left side ORVM (when switching to reverse gear)
- Sunroof with auto close
- White accented interior trim
- Memory seats (front only, linked to individual keys)
- heated seats (front only)
- Puddle lamps on all 4 doors and 2 ORVMs
- Footwell and door accent lights (front only)
- Upgraded (albeit underwhelming) stereo
- No spoiler (later added a VF Director model lip spoiler)
- Foglamps
The SV6 ride was a bit too harsh on 19" wheels, most came with a stupid spoiler and it did not have most of the creature comforts I wanted.
