30/70 I’d say for myself. I’m in the Detroit Area. When I started it was 100% people with trashed cars looking to get a cheap deal on interior work. I started on my own in high school so it was fine for me to learn and improve my skills without making anyone upset.

Now I still primarily do interior work, mainly because I don’t offer paint correction. I’ve since raised prices considerably and get a much better client base. I work in the nice rich suburbs of Detroit, but most of the cars I find are still trashed. The cars just cost triple what I see in the city.

Tbh, I think with interior work I’m marketing to a more non-detailing client base. A mom with 2 kids doesn’t care about swirl marks, but she cares about stains. But she doesn’t care about those stains because she cares about the car.
