Huh? He sells detailing supplies, tools, and tool storage. Would you buy this sort of stuff from someone with a beat up car and a messy garage? Rusty tools? Are you seriously conflating marketing with a legit mental health issue?
He's providing an example of what your garage COULD look like. Its a fantasy set up with fantasy vehicles in it. People see that and will be inspired to organize their garages.
Here is a pic of the OG:
This is a Sonic product he sells.
He offers a wide range of garage related/inspired products.
For me personally, I took the wife and kids on a side trip to Stuttgart to visit the Porsche Factory. In the museum, at the end of the ticket counter is a glass wall behind which, technicians restore cars. This isn't exactly the view, but from memory, its something like this:
Note wooden saw horses used to support this 917. I dig the white toolboxes, lighting, gray tile(?) floor. Everything is on wheels (makes sense). The parts rack looks like something I think I'd make if a do a build. The white a gray theme is pretty consistent with Porsche. And its deliberate.
I've never been to the Ferrari factory, but it famously has plants (because why not?). I spy what looks like gray Lista boxes left background.
Penske Racing in NC:

Classic Snap on red KRLs supported by multiple carts at each bay. Classic old school racing look. I love the idea of having more than 1 cart surrounding the vehicle. I could totally see doing something like this.
POINT IS: My future stoney garage (may call it "Castle Wolfenstein") won't look anything like these garages. But it probably will be inspired by all of them. Maybe a bit more drawer organization than I have now, maybe house plants, probably multiple roll carts for the very different things I work on. And maybe more wooden stuff, just based on that one picture.
Obsessed garage offers garage specific products that I might explore. He's put a lot of effort into thinking through what he sells. Yeah, he's not a mechanic, he's a business owner. Get over it.
