Aygo Gasoline vs Yaris Diesel

Hi am thinking of leaving my Yaris D4D old model, and getting me an Aygo because of the high fuel prices. I don’t see any sense of driving the diesel further because it’s everywhere tarier like a gasoline from the tax,insurance, inspection, partly at the tank, maybe even the spare parts. Is it worth changing from diesel to petroler? My driving performance is so about 40000km a year. Would therefore like to take the Aygo because the consumption is about the same mi t the Yaris Diesel ,and just insurance , tax and so on is cheaper. Would get along with the smaller car also because the Yaris I have hardly ever used properly. Would the pay off ?? Greeting froggi
