create app for android and iphone
change the car image on the app
add a "Search Cars" button between "post an AD" and "Logout"
the "search cars" button would send the customer to a page like the "buy page" of the site
the cars would be listed newest at the top by default, and the user can sort by newest to oldest, oldest to newest, price high to low and low to high
on the buy page would also have search by category and under the search would have an advanced search
the user would be able to select cars to compare.
the ad would show the featured image of the vehicle, the title of the car, ex color, mileage, body style, price, ("or best offer and Finance available" if any) details button and add to watchlist button, last it would have all the enhancement that was purchased.
create a car detail page of each listing
create a watchlist
all of the above should be the same as the website
allow the user to change their password, and add "Phone #" field, and "Dealer #" to the registration (this would be on both the app and site, as both are linked)
Make the ad upload faster (when placing a new ad maybe if the ad # is generated first then the images are automatically saved to temp file and as the rest of the ad is being completed to images would placed in the associated ad/file – this way the ad would be uploaded to the site faster, whether using the app of the website when uploading new ad)
allow user to view current and pass posted ads, and allow for changes/corrections to be made, and allow the user to emial himself the template if he forgets to press the email button at the end.
