A newer small car would use noticeably less fuel than my current one, but the insurance quote surprised me. Once I include the higher premium, registration differences and the money tied up in changing cars, the fuel savings look much less impressive. I drive a fairly average amount, mostly city errands. Has anyone built a simple ownership-cost comparison that doesn't pretend they can forecast every repair? I'd like to see the break-even logic before getting distracted by advertised mileage.
Comparing fuel savings with higher insurance on a newer model
Safety-critical vehicle advice should be treated as general discussion; use qualified repair help when a fault could make a vehicle unsafe.

The ad mileage numbers are doing a lot of heavy lifting there. Around town, stop-and-go tends to make the newer car look smarter on paper than it feels at the pump.
And then you sit in traffic with the AC on and the savings go home early. The spreadsheet never mentions that part.

I’d look at it as monthly cash flow first, not fuel savings first. If the payment, insurance, and reg jump more than the petrol bill drops, the newer car has to save a lot just to break even. On city errands, that gap usually looks smaller than people expect.
That’s how I’d do it too. I swapped cars last year and the fuel savings were real, but the insurance nearly ate them up on its own.
