The main problem is that the application has too many shortcomings. For example, there are no auto-suggestions on the screen, so it is hard to choose cars. Another problem is that when choosing a model from a list, the screen freezes because there is no progress indicator. Finally, the price comparison feature does not work properly. Other than these issues, everything else works fine. I like how you can filter the car models and then add them all at once. If someone would do this automatically as soon as they type something into one box or another, this will help reduce errors (and thus save money). Also, the prices should always be sorted alphabetically if possible, which means the "Add" button could become useless. Overall, though, it's good.
