When you make a car, you can configure BRAND

These are real brands that are already presented: (and you will get a logo)

• jaguar
  
• landrover
  
• lotus
  
• mazda
  
• nissan
  
• pagani
  
• porsche
  
• bentley *
  
• chrysler *
  
• dodge *
  
• ford *
  
• jeep *
  
• maserati *
  
• mercedes *
  
• plymouth *

* = seems not used currently anywhere in the game

Also note, these names are case sensitive.
So these will not work if you use uppercase letter. (eg. its not Nissan, its nissan)
And of course there are 49 fictional brands also.(not listed here)

I would suggest you write your car brand even its not at list. Don't leave it empty.
