The new car smell is actually is a complex mixture of volatile organic compounds (VOCs), primarily alkanes and substituted benzenes along with a few aldehydes and ketones.
Individual components of new car smell probably aren’t harmful at the concentrations found in cars, but the cumulative effects of long-term exposure to the total mix of VOCs could pose health problems. Fortunately, high concentrations of these compounds quickly dissipate just a few months after manufacture. And although VOC concentrations can reach unhealthy levels in a closed vehicle on a warm day, the air-exchange rate in a car is high when someone opens a door, rolls down a window, or turns on the air conditioner.

I’ll take “shit people who can’t regularly afford a new car say (like me)” for $600, Alex.
I’ve always wondered if that was the source of the smell.
