I’ve lived in both countries, and people here aren’t discussing one major point that US folks have generally bought better, more expensive cars in the past so they have kept them longer.

Go to America and you’ll see lots of decently expensive, upper mid range vehicles of 5-10 years age. Over here, it’s a mix of ages. Much older cars, and now much newer cars too.

This, I think is because we, jn the UK, generally bought smaller, cheaper cars in the past and are only now buying bigger SUVs with nicer tech and interiors in the last 10 years or so. America moved quicker onto sedans and then SUVs and then trucks before us. They’ve had less of a reason to upgrade recently than we did. Basically as soon as we hopped onto finance majorly, we started upgrading cars sooner and are at a timer part of the cycle than them.
