Family of 4 - Mom/Dad and two little children.

What is the car to get (fuel consumption is NOT an issue) that.
1. Is reasonable to insure
2. Is cheap to service
3. Is common (Holden Commodore - Ford Falcon etc) for tyres etc

I have had a look at drive.com.au but I need to narrow it down.

Quite like the SV6
