Iterating Through Cars:

The function iterates over a list of cars specified in the cars parameter. Constructing URL:

Builds the URL for the AutoTrader search based on the criteria and the current car in the iteration. Opening the URL in Browser:

driver.get(url): Opens the constructed URL in the Chrome browser. Waiting:

time.sleep(5): Pauses the script for 5 seconds to allow the page to load and prevent potential issues with dynamic content. Page Source and BeautifulSoup:

source = driver.page_source: Retrieves the HTML source code of the current page. content = BeautifulSoup(source, "html.parser"): Creates a BeautifulSoup object to parse the HTML content. Checking for Results:

Tries to find the number of pages by searching for a specific pattern in the page content. If the pattern is not found, it prints "No results found" and moves to the next car. Pagination Loop:
