In administrative panel need to simplify the "Create car" page forms. 1. Allow add new Make, Model, Variant, Color, Location asynchronously directly from "Create car" page. (create a button for this function directly in the Make, Model, Variant, Color, Location field on the right side) 2. Add "type hint" function to Make, Model, Variant, Color, Location fields witch will narrow the categories in the drop box, depending on what letters imputed. 3. For "Transmission" instead of drop down, make check boxes. FAT CAT DAT IAT. 4. Instead of "ETA Auckland" field, make a calendar where will be possible to select date. 5. Add a function to import cars on the website directly from EXCEL file. (sample of the excel file is attached) Front end: 1. In the "CARS IN STOCK" catalog, add price to the car cards above car tittle. 2. In the "CARS IN STOCK" catalog, when you point at the car, small window fade whit two more photos of this car.
