You can use the Exploring Outliers analysis if you want to have JMP identify outliers for you
Analyze=>Screening=>Explore Outliers
JMP Help has a good deal of information on how to run the analysis.
You can also manually explore your data by setting up a Data Filter
Rows=>Data Filter
If you choose this route, you can setup the Data Filter to filter on Prices, Ages and Odometer Reading. Then you can open multiple platforms such as Distribution, Graph Builder etc. and the displays will automatically change as you modify your selection criteria in the Data Filter.
JMP Help also has details on how to setup and run the Data Filter
