Just like every labor/trade/skilled based profession, people's perceptions are going to run the gammot. From the corner car wash guy making $8 an hour to the Kosillas, Mike Phillips, KB, Renny Doyles, Rasky's and ^^McGoverns"" of the profession.
BTW, there are many future Kosillas, MP, KB, working those $8 car washes right now. I was one who grew up learning my skills by trial and error, no mentors or Internet forums. Now I would say I'm in the hobbiest category, but would love to bump up to where Zach and Chad are at.
The general public has no idea what goes into a 50-100hr detail. Most of the public outside of the car show, detailing industry think it takes 4-6 hrs to get their cars perfect. But 90-95% of the public would be 100% satisfied with a one step correction. Wait, 90-95% are happy with a touchless wash once a month and a vacuum/wipe down every 2-3 months
I would guess depending on your market, most people wanting a "full detail" would expect an exterior wash, one step, vacuum, light extraction of carpets/upholstery and a maybe a sealant. $200-400 for that, 6-10 hrs. Now, when I think "full detail" I imagine wheels off, suspension cleaned, badges removed,seats removed, trim taped, two-three step correction, and high end coating/sealant applied. Price $800-5,000plus. See above video of McLaren F1. If I had to guess I would put that detail in the $10k plus category, plus travel expenses for each detailer.
