cars inflating faster than overall/average inflation of the economy is significant.
I suspect the reason is that a car's parts are numerous, and because specific inflation affects different components, there's a good chance that a car's component has more inflation than other products in the economy.
And because inflation has an expectation driven aspect, suppliers that know inflation is happening is going to raise their prices more to combat it pre-emtively. This happens throughout the entire supply chain.
Thus, the end result is that a car's inflationary pressure is higher.
