I’m on the reversed process. After pleasing myself with a 2017 BMW 3-Serie Touring, I’m about to buy back my leasing and sell this car for a late 2000’s Honda Jazz. The shock will be abrupt but according to my calculation, I would be able to save 630.- monthly compared to my current car situation.
My choice is also turned onto a 100hp atmospheric Japanese petrol engine, manual gearbox to reduce failure risks. Since I live close to the French border I’ll be able to fill it with E85 (little by little to let the ECU adapt to this new ethanol-based fuel). Surrounding gas stations currently sell at 0.80 euro/liter. Even with a slight increase in the average consumption (+/- 0.5l/km) the operating cost dramatically drops.
I’ve already experienced this fuel swap with a 2003 Toyota Yaris bringing the ratio to 80% Ethanol / 20% unleaded 98 with absolutely any issue (of course you won’t do that if you’re still under warranty).
