is the executive a nicer ride then the berlina, are the body shapes different at all?
The berlina and calais have Independant rear suspension (IRS) which means its a bit more of a comfy ride.
the differences have already been mentioned, the exec is stock bottom of the range while the calais is top of the range (a calais isnt actually a commodore
but lets not get into that haha)
the difference betten the berlina and the calais are just the little luxuries that most can live without
berlina - single zone climate control, thinner chrome window surrounds, I dont THINK the seats are fully electric, single CD player, different wheels, different patterns on seats
Calais- Dual zone climate control (two different temps at once), reading lights in the back, 'map lights', lights in the bottom of the doors,
10 stack CD player, Fog lights, and depending on what series (series 1 or 2) the interior will be much different
Heres some pics to compare, youll be able to tell which is which
