Full valet parking generally includes a more thorough cleaning of the exterior and interior, as well as the application of a wax or sealant to the paint, and a dressing for tires and moldings on the outer plastic and rubber. A mini valet is what most do as a way to keep your car tidy and well-maintained (in addition to regular service), so everyone has their own thing. If your car only feels clean after a full service and you use it a lot, a full valet service every six months may make sense. On the other hand, if you drive your car relatively infrequently and you're a normally tidy person, the only time you might want to do a full valet service is before you sell it.
What does a full valet service entail? well, it means cleaning everything that needs cleaning. For example, the exterior of the car is dirty, the interior console, dashboard and vents are dirty, the seats are dirty, the carpets are dirty, and the door moldings are dirty, so you need a full valet. While it might be smart to assume that it will take a little longer, it's generally a good idea to ask the valet service how long they think it will take once you get there. It's just that car details are used in American English, while valet parking is used in British English.
I don't expect a valet to include removing the wheels and cleaning the engine, but this also depends on the particular valeter to decide what level it includes. I have my sl63 valet and detailed once a year, the spare tire & of the engine boot looks like it just came out of the factory. Personally, I don't think the details of the car are enough to have an established routine such as: washing, clay bar, polishing and waxing, but rather cleaning areas that are not usually cleaned and repairing parts that may be damaged, including paint repair or wheel renovation. He became interested to know how different it is from car details because, according to him, every time he typed the word “valet service in the Google search box”, the details of the car appeared in the results.
If you have a pet, or have a particularly stubborn mess inside the car, there is likely to be a full valet on the cards. And secondly, because regularly cleaning and keeping your car clean can mean that your car will sell for more than it would if it weren't cleaned regularly by a professional. As you can see, valet parking offers a very extensive method of cleaning your car and ensures that you are left with a car with higher resale value, driving pleasure and a pleasure to look at. While a valet does not require car maintenance in any way, as a full service can be, consider doing a full valet service at least once in the life of your car, if only before you sell it.
I think a lot of people have come to relate valet parking and car detailing as two separate services, when in reality simply due to the bad press of low quality valet parking services available these days, they are still the same and only different terms used by different countries. Carrying your car to a valet is like taking your dress shirts to the dry cleaner—those stubborn stains that you can't get rid of will probably disappear when you get it back.
