One tank of gas amounts to around 700km.
After 5 years it would amount to ~175.000km. This car will most likely not live for 20 years without mayor replacements and repairs.
I have a 2001 BMW 330i that's on around 363k miles (~580,000km) and still running the original factory drivetrain. The only parts replaced so far are wear parts in suspension and brakes (common with EVs) and some coolant pipes (probably also needed in EVs).
