Css selector returns blank list-CodePudding

Hi there I am new to scrapy and web scraping in general and I am having a hard time with trying to scrape from this website: https://www.webuycars.co.za/buy-a-car

My goal is to scrape the car data like the name, price etc from the page

I started with

scrapy shell "https://www.webuycars.co.za/buy-a-car"

I then did

fetch("http://localhost:8050/render.html?url=https://www.webuycars.co.za/buy-a-car")

I am using splash with scrapy because I have come to the conclusion that the page was created with javascript I then tried to send some requests but after a certain point in the html of the page I start getting blanks(this is what I assume to be javascript created) For example

response.css("div.col-lg-3.col-md-4.col-sm-6.mt-3").getall()
[]
response.css("div.result-item-title").getall() 
[]
response.css("div.result-item-title").get()
response.css(".result-item-title").getall()
[]

Getting the title seems to work but nothing else I have tried works

response.css("title::text").get()
'WeBuyCars | Sell Cars For Cash | Free Online Vehicle Valuations'

I have been trying to do these requests to make sure I get results before I program the spider and implement it properly into my program. I set my user agent in the settings file. I have looked at all the source files to see if there was a json file containing what I needed but there isnt one. I am not sure what else I can do. I have been stuck on this problem for quite a while and I would appreciate any help.
