Japanese and domestic brand share of the used market by state
Comparisons

Michigan Lots Are 74% Domestic. Hawaii Is 51% Japanese.

Where a car was designed still decides what sells, three decades after that stopped being an argument about quality. The map is sharp enough that you can guess the state from the brand mix alone.

The Diesel F-350 Asks $25,126 More Than the Gas One

Thirteen Car Brands Died in America and the Total Never Changed

Hybrid versus petrol car mileage by vehicle age
Comparisons

Two-Year-Old Hybrids Have 24% More Miles Than Petrol Cars the Same Age

The Nissan GT-R Went 15 Years Without a New Generation

Wheelbase as a share of vehicle length by era
Comparisons

Cars Got Longer and Their Overhangs Got Shorter. The Wheels Moved to the Corners.

The most visible change in car design over thirty years isn't size — it's proportion. The wheels are further apart and there's less car hanging past them.

Average annual mileage by car model comparison
Comparisons

A Corvette Covers 2,738 Miles a Year. A Ford Transit Covers 15,135.

Average fuel economy by EPA vehicle class
Comparisons

Small SUVs Are the Most Economical Class in America. That Says More About the Classes Than the Cars.

The EPA sorts every car into an official class. Rank those classes by fuel economy and the result makes no physical sense — until you look at which powertrains land in which box.

Cars Grew Four Inches Taller and Four Inches Wider in Twenty Years

The car you're replacing is smaller than the one replacing it, whatever the badge says. I measured the dimension data across two decades and the growth is uniform, relentless and mostly invisible until you park.
