Toyota Corolla (2017) gets 30/36 mpg and cost $13K with 80K miles on it. Insurance $100/month for maximum coverage. I have had it since 2019 and have never had any maintenance except spark plugs (once), battery (once) and tires (once), and oil changes. So I have spent maybe $1000 on maintenance in 6 years.
Pros: low maintenance costs
Vehicle:
Toyota Corolla
Mileage: 128747 km
O drove my Corolla to the point the spark plugs weren't firing and the car wouldn't start. I changed the plugs and it ran great after that.
Pros: ran great after replacement
Cons: wouldn't start before
Vehicle:
Toyota Corolla
UPDATE: owners manual calls for replacement around 120k so I'm not that far behind i guess. Still went out and bought 4 new plugs and installed them. $80 at the dealer
Noticed before the LTFT was -6% and now its back to 0%.
Pros: LTFT back to 0%

Mileage: 120000 km
