Yes, correct! There is about a factor of 3-4x missing I would estimate. 
Another way to estimate prices is to convert to ounces of gold and then back. Gold is money, currency is not (it’s a non-backed IOU). In 1946 an ounce of gold was $35, which means a car costing $900 was 25.7 ounces of gold. Even with today’s suppressed gold prices (suppressed by big bank short selling, central bank leverage and derivatives not covered by physical metal), that would be around $31000 today. As you can see, a much better measurement of value
In the game we will calculate prices in money units, not currency, but display it in currency units. Sounds weird, but that’s the only good way of tracking actual value throughout the game and converting to currencies.
