How to sort a list of objects by dictionary value?

How do I sort this by the selected dictionary value in Person?

Example: List of orders "Face" by value "cars" in descending order.

Is this possible with one of these bizarre lambda / linq equations?

public class People 
{
    List<Person> Persons { get; set; }
}

public class Person
{
    public Dictionary<string, string> cars { get; set; } 
    public Dictionary<string, string> houses { get; set; } 
    public Dictionary<string, string> banks { get; set; }
}

................

People people = new People();

people.Persons = new List<Person> 
{
    new Person 
    {
        cars = new Dictionary<string, string> { { "volvo", "340050" }, { "bmw", "50545000" } }, 
        houses = new Dictionary<string, string> { { "mansion", "100040000" },{ "cardboard box", "112" } },
        banks = new Dictionary<string, string> { { "swiss", "12500330000" }, { "camen", "12000000" } }
    }, 
    new Person 
    {
        cars = new Dictionary<string, string> { { "volvo", "34023200" }, { "bmw", "5003300" } }, 
        houses = new Dictionary<string, string> { { "mansion", "1000330000" },{ "cardboard box", "277" } },
        banks = new Dictionary<string, string> { { "swiss", "12500044000" }, { "camen", "12000000" } }
    }, 
    new Person 
    {
        cars = new Dictionary<string, string> { { "volvo", "3554000" }, { "bmw", "50023200" } }, 
        houses = new Dictionary<string, string> { { "mansion", "1006600000" },{ "cardboard box", "244" } },
        banks = new Dictionary<string, string> { { "swiss", "125000544000" }, { "camen", "12000777000" } }
    }
};

EDIT / EXAMPLE OF RESULTS:

The result will be a new or reordered list based on the value contained in each person’s dictionary

Person β†’ cars β†’ {"volvo", "34023200"}
Person β†’ cars β†’ {"volvo", "3554000"}
Person β†’ cars β†’ {"volvo", "340050"}

A new or reordered list will look something like this:

people.Persons = new List<Person> 
{
    new Person 
    {
        cars = new Dictionary<string, string> { { "volvo", "34023200" }, { "bmw", "5003300" } }, 
        houses = new Dictionary<string, string> { { "mansion", "1000330000" },{ "cardboard box", "277" } },
        banks = new Dictionary<string, string> { { "swiss", "12500044000" }, { "camen", "12000000" } }
    },
    new Person 
    {
        cars = new Dictionary<string, string> { { "volvo", "3554000" }, { "bmw", "50023200" } }, 
        houses = new Dictionary<string, string> { { "mansion", "1006600000" },{ "cardboard box", "244" } },
        banks = new Dictionary<string, string> { { "swiss", "125000544000" }, { "camen", "12000777000" } }
    },
    new Person 
    {
        cars = new Dictionary<string, string> { { "volvo", "340050" }, { "bmw", "50545000" } }, 
        houses = new Dictionary<string, string> { { "mansion", "100040000" },{ "cardboard box", "112" } },
        banks = new Dictionary<string, string> { { "swiss", "12500330000" }, { "camen", "12000000" } }
    }
};

; , KeyValuePair < > .

Dictionary<int, string> myDictionary = new Dictionary<int, string>();
foreach(var item in myDictionary)
// item is a KeyValuePair<int, string>, enumerated in order of their insertion into the dictionary

, , LINQ:

Dictionary<int, string> sample = new Dictionary<int, string>
{
   { 1, "Sample" },

};

var orderedList = sample.OrderBy(x => x.Value).ToList();

List<PersonCarDetails> allStuff = new List<PersonCarDetails>();

foreach(var person in persons)
   allStuff.AddRange(person.Cars.Select(x => new PersonCarDetails { PersonId = person.Id, CarName = x.Key, CarId = x.Value }).ToList());

 // allStuff now contains a list of PersonCarDetails, and then you can order that:

 var orderedList = allStuff.OrderBy(x => x.CarId).ToList();
