Splash is unable to extract elements - web-scraping

Question

I am trying to scrape https://www.lithia.com/new-inventory/index.htm.
But it seems that the slash is unable to extract simple elements on the page.
I tried to extract an element from the page with the appropriate XPath using either Scrapy project (python) or slash site (http://0.0.0.0:8050/), but Splash is unable to extract the element.
Code (I have simply so it is easier to convey and debug) :
import scrapy
from scrapy_splash import SplashRequest
from time import sleep
class CarSpider(scrapy.Spider):
name = 'car1'
allowed_domains = ['lithia.com/']
start_urls = ['https://www.lithia.com/baierl-auto-group/new-inventory.htm']
def start_requests(self):
for url in self.start_urls:
yield SplashRequest(url = url,
callback = self.parse,
endpoint = 'render.html')
def parse(self, response):
sleep(5)
year = response.xpath('//span[contains(#class, "facet-list-group-label") and contains(text(), "Year")]')
sleep(5)
yield{
'year': year,
}
It returns:
{'year': []}
Meaning it is not extracted.
I check the Splash site (http://0.0.0.0:8050/) as well, and lots of element is not displayed in the HTML output. It seems like there is some rendering issue.
Following that, I came across this page (https://splash.readthedocs.io/en/stable/faq.html#website-is-not-rendered-correctly), informing possible debugs of the rendering issue by Splash:
I have tried:
Turning off private mode.
Tuning splash:wait()
setting splash:viewport_full()
adding splash:set_user_agent
enable it using splash.plugins_enabled
splash.html5_media_enabled property to enable HTML5 media
But so far, I am still unable to extract the element. In fact, lots of other elements cannot be extracted as well, just giving the element above as an example.
Please Help.
