Yeah, regarding NET vs GROSS there’s no universal way to calculate the conversion. The way the people rated their engines back then was pretty shady, in order to get higher power ratings.
Although one85db articule is about powertrain loss (flywheel hp vs hp at the wheels) the principle is rather the same in net vs gross.
Regarding the money thing, killrob once said that the money in automation was roughly based in 2010’s dollar, and he suggested to change the value to gold and then back to money, simply because the inflator calculators are horrible wrong, you always get really really low prices.
So “I came up” with the gold method, simply calculating the ounces of gold of the car and then converting back in gold for the year the car is supposed to be:
An example of how it works:
The bad thing abaout that method is that the sandmode prices are higher because they don’t count as reusing an existing factory and production shifts and staf, so using a markup you will normally use in tycoon mode (30% or higher) you end up with a slighty overprice car, but still closer to the normal price back in the day.
