Hello,
Our theme supports the Dokan plugin. You can check the demo where the Dokan plugin is activated here https://xstore.8theme.com/demos/2/dokan/
If you use our theme you probably know that it has search by product title, descriptions, SKU, posts and pages. Unfortunately, we don’t have such option to add the search by distance. So, you probably need to look for an additional plugin to implement this.
We have the demo site of the carwash https://xstore.8theme.com/demos/2/carwash/ Maybe you could implement this for the car dealer site.
And check the following demos https://xstore.8theme.com/demos/corporate/ and https://xstore.8theme.com/demos/marketing/ Maybe its design will suit the employer site.
Regards
