The MUM car

We bought the MUM car for Sandra's birthday 10 years ago and it has proved to be mainly reliable and comfortable. Perhaps our weather could have suited it better. There's a bit of mildew on the hood and I still resent the treatment from Audi when the clutch went at 25000 miles - two minutes out of warranty.

With her birthday approaching again I have been thinking about her motoring costs
Here is the arithmetic for its 11th year

Depreciation £500? ( it was written down to nothing in 2008 but may still be worth £3000)
Insurance  -   £300
Service -       £300
Fuel  -         £2000 based on 25mpg and 8000 miles
Road tax      £460

   Total cost £3560 - 44.5p per mile

Or would it be more sensible to buy a new one where the figures might look like this...

Depreciation £5000  (20% of £25000)
Insurance  -   £300
Service -       £100
Fuel  -         £1250 based on 40mpg and 8000 miles
Road tax      £105

   Total cost £6755 - 84.4p per mile 

Oh dear I forgot the cost of finance for a new one - That could be another 15p per mile.

I think we'll probably keep MUM going for another year.
