vauxhall insignia Saloon

I am looking for second hand cars, with automatic cars. Just researching various cars and now I feel like "Vauxhall Insignia" saloon is a better choice for a family. But, i am not sure which model to buy . I see a lot of 2010 and 2011 models for sale ? Which model is good ? Hows the automatic car?

Firstly, Is Vauxhall Insignia a better choice ? Any user experience ?
