I just want to confirm what you want us to do by "adding 5 other vehicle related characteristics". Do you mean we have to add 5 more models (meaning new objects), or do we just have to add 5 more properties to the same model iX35?
Add 5 Properties to your class.
That is what I did, and only thing that really makes sense..
when you print it out you will give your object (the ix35 or another object I dont think it maters as long as the object comes from the class)
values for each of your new properties and print it.
I believe what is being tested here is extending of a Class
