Hello, I need some help with a ArgoUML assignment. The assignment was originally a UML diagram of a fleet of cars each week, we make changes. We had to add inheritance last week.

I turned it in and got feedback. I can't move on to the next part until I fix what is wrong but I genuinely don't understand how to fix it. For instance, I need to add missing parameters but I don't know what to set them as.

Could someone help me out here? and perhaps explain a bit what they did so I can understand.

I'm attaching a png of the diagram from week 1 and then week two. I've also attached the feedback given for week 2. Thank you for any help.
