Overall Captiva & SX MY 12 Series 2 is a good car and value for money compared to other cars in same category of SUVs. It's smooth to drive and the interior is beautiful.
Good pick up with acceleration, and yes massive improvement in fuel economy (avg. 8.2 to 9.2L or 100 Km).
Good features as standard. Last row seat needs more space, driver area needs better leg space especially near your left foot and with this price if Holden gives roof rails would be better.
Lastly do not believe the rubbish that some guys post here , I am driving this since Sep-12 and it's a fantastic car.
