Following a service this week I've been told I'll soon need a new battery for my car - at a cost of $540...
Given I'm used to spending under $200 with previous cars, I rang around a few places - Repco offered it to me for the bargain price of $1160! The best I've found thus far is $336 ("Ultra" brand).
So if anyone can recommend where I can find well-priced batteries, I'd appreciate it - it's a model called a T110.
Apparently, the battery for my model of car (a diesel Mazda 6) has specific requirements due to the stop/start and iEloop (capacitor to store braking energy) systems. So technologies that I thought would save on-going running costs and reduce my environmental impact through reducing fuel consumption end up costing me more through needing some flash-as battery.
This raises a wider issue - the (at least initially) hidden cost of owning modern cars. I had no idea when I purchased my car 2 1/2 years ago I'd be needing to spend that much on the new battery; that replacement tyres are $500 each... And this is on a car that cost only $62k new.
Car reviews tend to not really cover this 'total cost of ownership', but it's important to have this information to hand when making such a costly purchase. As others have pointed out there's also the untested longer-term reliability of the complex technology in modern cars, which will no doubt come at some cost when/if it goes wrong...
