I can't event get past 3rd step in car app first lesson

The best thing to do when asking for help is to use the Help button in the step so that it includes your code so we can see what you have tried. Without being able to see your code, we can only guess, and we will probably be wrong. Since you already started this thread, you’ll have to manually paste your code in here using the following method.

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').
