Configure Table cell in model class
There are lot of ways to organize an architecture. I will explain how do I understand some of them. Read about MVC and MVVC patterns.


First of all, it would be better do divide all code related to requests and code responsible for UI.
Creating a model class is a good way. Model can only keep and parse data. It shouldn't contain any business logic.
You can create one more type class. Such as presenter or viewModel. This class would manage all contains in this module. Contains the cars array in your case. And here you can ask the ServerInteractor class to run the requests. 
All code related to requests would be better to keep in ServerInteractor (or LocalInteractor). 
It is a good practice to write methods smaller if it is possible. For example in your cellForRowAt method you can divide all code such as "cell.date.text = entry.date" to the separate method


I wish  it would be useful )
