Running costs and where the numbers come from
Your own costs come from what you log. The public running-costs pages are built from what owners across Elferlog have logged for that generation.
Total investment is your purchase price plus everything you have spent on the car, minus what you have received for parts sold.
The experience fee is what the car has cost you to own so far — investment against the car's current standing, spread across your ownership.
Generation pages show typical costs from the community's real entries, not from a price list.
Only aggregated figures are ever public. Your individual prices are not.
