I pay car tax approx £20 a month D.D
Car Insurance £15 a month, sometimes I pay annualy to save £15.
I get my car M.O.T'd by the council £45. They are not connected to any garage & I trust them.
I use a local garage for repairs that is also a scrap yard, so no huge fancy building to run, its kind of an old warehouse type lock up. They charge £35 an hour labour, run by husband & wife.
They service it annualy for £100.
I spend approx £40 a month on petrol, so I dont go far!
£40 a tyre, again from a local tyre centre that is not a huge chain.
Repaurs I tend to pay as I go, but really I should put £20 a month away for this 
If i got a newer car I could save a bit on car tax.
