Sure! Here is an example code in Python that creates a `Car` class:

```
class Car:
    def __init__(self, make, model, year, color):
        self.make = make
        self.model = model
        self.year = year
        self.color = color
        self.speed = 0

    def accelerate(self, speed):
        self.speed += speed

    def brake(self, speed):
        self.speed -= speed

    def get_speed(self):
        return self.speed
```

In this example, we have defined a `Car` class with a constructor (`__init__`) that takes in four parameters (make, model, year, and color) to initialize the car's properties. We have also defined three methods (`accelerate`, `brake`, and `get_speed`) that manipulate the car's speed property.

To create a `Car` object, we can use the `Car` class like this:

```
my_car = Car("Toyota", "Corolla", 2022, "blue")
```

This will create a new instance of the `Car` class with the given properties.
