I am new to x theme and word press in general, I am looking to showcase cars i am currently selling with images and a description, what is the best was to do this, do i need to create a individual page for each car or is there an easier way such as using a portfolio?
You can use portfolio to showcase cars with description. Browse to WordPress dashboard >> Portfolio and add portfolio items. Set portfolio page as mentioned in this article : https://theme.co/apex/forum/t/features-portfolios/98
