There's a key reason why 2015 could be the best year ever for US auto sales

Automakers reported US October sales on Tuesday, and sales were good.

Actually, scratch that — they were insanely great.

Nearly every major automaker reported sales that exceeded analysts expectations. The US market is now running at or near a feverish 18-million annual sales pace.

If 2015 closes with 18 million new cars and trucks sold, it will beat the best year on record: 2000, which came in at 17.4 million.

So what’s driving this torrid sales pace?

Simple: The cars currently on the road are old.

Very old.

The average age of a vehicle in the current fleet is roughly 11 years. That’s ridiculous by American standards.

American just don’t drive old cars. Unless a massive recession destroys their access to credit and takes away their jobs. In which case they drive their cars until the wheels come off.

Well, the wheels are coming off a lot of cars. That’s why as the economy recovers, Americans are buying, and buying, and buying some more.
