Running costs depend on how much you drive.
You can't ask someone how much they spend on their car each week.
It doesnt work like that.
You have the cost of petrol.
The cost of registration.
The cost of anything that needs fixing, replacing, repairing etc.
All the things that you need at regular intervals, spark plugs, oil, filters (air, oil, petrol) leads, brake pads, wiper blades, then there are the other things that need replacing, like tyres (expensive things!) and the list goes on.
Once you get a car, don't expect to ever have any money ever again.
And all those things I listed above, those are expenses that have to come before luxuries, like, lowered springs, window tinting, aftermarket wheels, fluffy dice, neons and all that other crap that people seem to emjoy so much.
