CFD Post-processing

Hello everyone! I am working on rolling out a CFD tutorial on external flow simulation on a Formula Student car possibly with the data set. Here's a little sneak peek:
While this is going to be a comprehensive tutorial, I am looking for ideas/suggestions when it comes to post-processing results. Please feel free to share your thoughts in the comments section on what are some of the key parameters that you may want to study though both filed contour plots and XY plots in a simulation like this.
