It really really is a 'how long is a piece of string question.
So - road tax - we have 2 cars - 1 costs £20 per year, the other £160 odd (the bigger engined car is the cheaper)
Insurance - a [poster has said she pays £98 per year.... I'm very jealous of wherever she lives - I had, until very recently over 25yrs no claims, I'm a good risk in all the things they look at in insurance, and mine was still just over £200. For a new driver, you can be looking at literally £3,000. It takes into account your postcode, your job, all sorts of risk factors.
MOT - the actual cost of the test can be as low as about £40, but my cars generally need bits and pieces replacing or fixing for MOTs - I'm generally happy if I get change from £300, but, in fairness, that tends to be all my expenditure on maintenance. The newer your car, the more likely you are to want to 'keep it in good condition' and get scratches, repaired, etc.
Every couple of years, you'll need to replace a couple of tyres - can be from £30 each up to about £140 each (see above about having fancy cars)
It doesn't necessarily equate that you spend more on an oder, or even on a cheaper car.
Then petrol / diesel - depends not only on how many miles you do a week / month / year, but what sort of driving - long journeys, or lots of short ones. Sitting in traffic. etc.
There are so many variables it really is impossible to say.
