Hey all, I need some advice hope you could help. I was thinking of buying 2006 Commodore Executive 3.6 VZ auto. It's going to be my first holden. Some of my friends including my dad doesn't want me to buy the car due to the fact that it cost more to run compared to a 1.8-2.0L engine. My second option is Subaru Liberty 2.0L sedan. Could someone here give me some sample computations on how much the difference would be in terms of Petrol cost between two cars driving both city and highway. I was thinking by comparing the two maybe the difference is not that huge that its bugger all. and go ahead with Holden. Thanks in advance! I really appreciate your help.
