[@anilsrivastava8762]

Can you explain how to do this use case by LWC .👉Customers should be presented with a UI to view the list of cars
along with Name, Image, Maximum Load, and Cost

[@SALESFORCEPREDATOR]

This is quite an easy scenario. You just have to query the list of records for car object in auraenabled method and return it to lwc component. There assign the result to a list variable in the javascript file. Iterate over the list on the template file to show the required details. You can use @wire or even LDS(won't require soql and all)
