All their pricing is ridiculously high, I know a famous auto spa which costs SUVs for 16,000/- even for their favorite customers and charges exuberantly for others.
Cquartz coatings don’t cost a lot even their finest costs around 13k which they use on two cars. Car pro essence or other polishing agents are also low priced and used for many cars.
Rest is labor and their profit.
It’s personal choice whether to go for coating or keep waxing your car monthly, both need regular maintenance and proper care of paint surface.
