Turned Manual Follow-Ups Into An Instant, Car-Specific Answer For Cargentur
A personalized web page and AI chatbot for every mobile.de inquiry, restricted to the exact car a buyer asked about.
PERSONALIZED PER INQUIRY - RESTRICTED TO ONE CAR - CONDITION REPORT CLEANED - <2S PAGE LOAD
The problem
Every Car Inquiry Waited On A Manual Follow-Up.
Industry pain. A buyer inquires about a car on mobile.de and waits for someone on the sales team to follow up by hand. Every reply depends on a person being free, and response times suffer.
Cargentur's version. The system builds a personalized page for that inquiry and answers follow-up questions about the specific car automatically, with a real agent available the moment it's needed.
Every inquiry gets a page built for one car.
The moment a buyer messages about a car on mobile.de, Cargentur generates a page for that car alone: photos, specs, and the cleaned condition report, pulled straight from the file server.
In one screen
The Condition Report, Cleaned Of Pricing.
Cargentur's file server holds the inspection PDF for every car. Before it reaches a buyer, the system removes the pricing information and displays the cleaned report on the inquiry page.
A page per inquiry
One Page, Matched To One Car.
The page is generated the moment a buyer messages about a car on mobile.de, matched to that vehicle by its file-server ID.
When it's time for a person
One Click Hands The Conversation To Your Team.
End Chat or Talk to Real Agent both close the session and send Cargentur's team an email with the full chat history and a summary.
