Case Study · Automotive and Fleet
Every Buyer Inquiry Gets Its Own Page, and It Answers Back.
A buyer asks about one used car on mobile.de. Kodexo Labs built the system that turns that message into a private page for that exact car, with an assistant that answers questions about it instantly and hands the conversation to a salesperson when it matters.

01 · Overview
One Car, One Buyer, One Page Built the Moment They Ask.
A buyer sends a message about a listing on mobile.de. Seconds later they get a link that belongs to them. It opens a page for that single vehicle: the real photos, the specification tables, the equipment lists, the service record, the delivery options, and the condition report with the dealer's pricing notes taken out.
On the same page sits an assistant that has read everything about that car and nothing about any other. It answers the moment the buyer asks, keeps to CarGentur's own wording on price and damage, and hands the buyer to a real salesperson the moment the question needs one. Nobody at the dealership touches a step in between.
02 · The Problem
Every Follow-Up Question Was Somebody's Twenty Minutes
A used car sells to whoever answers first. At CarGentur, answering meant opening the file server, finding the right photos, reading a condition report, and typing a reply by hand. The specification named six things that had to change.
02
Replies Came Too Slowly
A buyer who waits for an answer has usually moved on by the time it arrives.
03
The Car's Photos Were Locked Away
Everything sat on the dealer's own file server, connected to nothing a buyer could open.
04
Some Cars Had No Description
The only record was a scanned report nobody could search.
05
Two Buyers, Two Different Answers
Price and damage were answered from memory, so the wording changed with whoever replied.
06
No Clean Route to a Person
A serious buyer had no direct way to get from a question to a salesperson.

03 · The Solution
Six Working Parts, One Page the Buyer Never Waits For
Each part maps to a requirement in the specification. Click through to see the screen it produced.
Page Generation
A Private Page, Generated on the Inquiry
The mobile.de submission triggers the build. The car is found by its own magicID, its images and description are pulled from CarGentur's file server, and a page for that one vehicle is published on cargentur.de.
Specification 4.1 · Page generation
Reading the Paperwork
Scanned Reports Become Searchable Facts
When the file server has no description, the condition report is read instead, the details are extracted, and the result is stored in a knowledge base so the same work is never done twice.
Specification 4.2 · File server and OCR
Condition Report
The Buyer's Copy, With Dealer Pricing Removed
The inspection PDF is cleaned of pricing information before it reaches the page, so buyers get the appraiser's full findings and nothing on the dealer's margin.
Specification 4.4 · Condition report cleanup
The Assistant
Answers About This Car and No Other
Every question is sorted before it is answered: company questions get standard wording, car questions are answered from that vehicle's record alone, price and damage follow CarGentur's approved lines, and off-topic questions get a polite redirect.
Specification 4.3 · AI chatbot routing
Handover
A Real Agent, One Click Away
Buyers can end the chat or ask for a person at any point, and the assistant offers the handover itself whenever it is unsure. The escalation notifies CarGentur directly.
Specification 4.6 · End chat and handover
Handoff Email
The Write-Up Reaches Sales on Its Own
When a session closes, the team receives the full conversation, a short summary, and the buyer's details, formatted to match the email structure CarGentur already uses.
Specification 4.5 · Automated handoff email
04 · How It Works
From a Message on mobile.de to a Salesperson's Inbox
Nobody at CarGentur touches any of the steps in the middle. Each step carries the specification section it comes from.
Step 1 · Inquiry · 4.1
A buyer messages about one listing on mobile.de
Step 2 · Find the Car · 4.1
The vehicle's own ID pulls its photos and description from the file server
Step 3 · Fill the Gaps · 4.2
Missing details are read out of the condition report and saved for next time
Step 4 · Publish · 4.1
A page for that car goes live on cargentur.de and the link is sent to the buyer
Step 5 · The Conversation · 4.3
The buyer asks. The assistant sorts the question into one of four kinds before it answers.
About the company · standard wording on sales, payment, and delivery
About this car · answered from that vehicle's record alone
Price or damage · CarGentur's approved answer, word for word
Off topic · a polite line that steers back to the car
Step 6a · Handover · 4.6
Unsure, or asked for a person? The buyer is offered a real agent and sales is notified.
Step 6b · End Chat · 4.6
The session closes with a summary of what was discussed.
Step 7 · Handoff · 4.5
Sales receives the full chat, the summary, and the buyer's details, in the format the team already uses.
A Supervisor Owns the Wording
Approved answers live in a library a supervisor can edit, preview in a sandbox, and publish now or overnight. Every change is logged with who made it and when.
Buyer Data Stays Protected
Traffic between buyers, the pages, and CarGentur's file server is encrypted. Chat records follow GDPR rules for consent, access, and deletion.
Nothing Fails Quietly
A file that will not open, a report that will not read, or an assistant that is down each raise a logged incident, and the buyer is offered a real agent straight away.

FAQ
What Dealers Ask Before Building Something Like This
The questions that come up in almost every first call about automating buyer inquiries.
Can the Assistant Talk About Other Cars in Stock?
No. Each page is tied to a single vehicle, and the assistant answers only from that vehicle's record. Questions about other stock get a redirect, not a guess.
What Happens When a Buyer Pushes on Price or Damage?
Those two topics have approved answers written by CarGentur, and the assistant uses them word for word. A supervisor can rewrite them at any time without a developer.
Does the Buyer See the Dealer's Pricing Notes?
No. Pricing information is removed from the condition report before the PDF is published on the page, so the buyer gets the inspection detail without the internal figures.
What if a Vehicle Has No Description on File?
The system reads the vehicle’s condition report and pulls the details out of it. If the read fails twice, the record is flagged for a person to check rather than published half-empty.
How Does the Sales Team Pick Up a Conversation?
Every chat that ends or gets escalated sends the team an email with the full conversation, a summary, and the buyer's details, formatted the way CarGentur's inbox already expects.
Does Traffic on a Busy Weekend Break It?
Each inquiry runs as its own page and its own session, and the setup spreads load across servers during peak periods. Uptime, response times, and error rates are monitored.
How Long Does a Buyer Wait for Your First Reply?
