Advice: Thinking of defecting.

[Poodle]

Honestly, you will struggle to find something more rugged and cheaper to maintain, £3100 all in to run a car is impressively cheap for somebody who doesn't do the maintenance bit themselves. It's the main reason i keep so many in the family tbqh. By the sounds of it you will struggle to find something as well maintained either, averaging 58mpg on a hilly commute is impressive and no doubt down to the condition of the car. You might save a bit on tax and insurance, but most newer cars will cost more on fuel, have bigger problems when they do go wrong and suffer much higher depreciation.

Don't get the Fiat! There's good reasons you don't see many around lol.
