Elizabeth Warren’s paper from a decade or two ago did a fair job doing some pricing comparisons of the day to turn of the century American household microeconomics and demonstrated the primary change in the past 100 years was the additional cost of a second bathroom.
Microeconomic comparisons are very easy to tweak to achieve a conclusion determined a priori. Some goods and services like electronics, air travel, communication, and transport become orders of magnitude cheaper over the course of the 20th century. Others like healthcare and housing on average get more expensive, especially in the latter half of the 20th century. If you want to show lowering costs of living, weight the model towards the former. If you want to show a higher cost of living, weight the model towards the latter.
The price of a model T in 1908 was $825 or $850 (google results vary). The median annual income was between $450 and $525 (again, sources vary). So a Model T cost 1.6 to 1.7 times the median income of a US worker. For a car that had no air conditioning, no radio, no airbags, and a top speed of 45 mph. Near the end of the production run (mid-late 20s) the cost of the model T had gone down by over half - thanks to production line manufacturing.

By comparison, the current US median income is just over $60k. You can buy many of these cars for less than half of that. Some less than a third: https://www.truecar.com/prices-new/kia/ Each of these cars is drastically safer, more comfortable, and with amenities like aircon radios and more.
