I hate the current method used to calculate the CPI. I am boring I prefer to use oz of gold. Yes, gold is very volatile but the US dollar is very volatile. Gold 1985 USD 327 per oz, therefore, the car is $17,900/ 327 = 54.74 AU oz Gold 2018 = $1320 per oz Car $26,300 , therefore, car = $26,900/1320 = AU 20.37 oz The car is dropped by 2/3 in terms of gold.
