Ditch the Paperwork: How I Trained AI to Manage My Vehicle Maintenance & Repairs

Hello, fellow AI explorers! Today, I’m excited to take you on a journey through the creation of MyGarage, an AI-powered tool designed to streamline vehicle maintenance, predict repair expenses, and keep comprehensive records—all with the ease of a custom GPT. 🚗🛠️

The Challenge: Why MyGarage Was Needed

Managing vehicle maintenance isn’t always straightforward. Between oil changes, brake inspections, tire rotations, and unexpected repairs, keeping up with a car’s service history can quickly become overwhelming. Paper records get lost, and spreadsheets require manual updates.

I wanted a simple, intelligent solution that would:

• Automatically retrieve vehicle specs from a VIN or make/model entry.

• Track and schedule maintenance based on manufacturer recommendations.

• Forecast potential repairs based on vehicle age, mileage, and common issues.

• Store service history and let users easily update it via natural language.

• Provide part recommendations and links to maintenance guides and repair videos.

With that in mind, I set out to create MyGarage, leveraging the power of ChatGPT’s custom GPT capabilities to deliver a seamless, interactive experience for vehicle owners.

The Collaborative Process: How MyGarage Took Shape

Building MyGarage wasn’t just about stringing together a few prompts—it was a deep dive into AI-assisted tool creation. The goal was to make a GPT that could function as a long-term vehicle minder, not just a one-off assistant.

1. Defining the Core Functionality

I started by outlining what MyGarage needed to do and how it should structure vehicle records. After several iterations, the core functionality took shape:

• Vehicle Workspaces: Each vehicle has its own dedicated canvas, allowing for structured tables, embedded images, and links.

• Automatic Data Retrieval: By entering a VIN, the GPT pulls specs like engine type, transmission, and dimensions.

• Maintenance Scheduler: Tracks oil changes, tire rotations, and major services, offering reminders based on usage.

• Parts & Repair Assistance: Provides recommended parts (with budget-friendly and premium alternatives) and step-by-step repair guides.

• Service History Logging: Allows quick updates by uploading invoices or entering details conversationally.

• Predictive Repair Forecasting: Estimates the next likely repairs based on vehicle age and mileage, helping users budget accordingly.

2. Refining the Master Prompt

Once I had a clear vision, I worked extensively with ChatGPT to refine the master prompt—the backbone of MyGarage’s functionality. Some key refinements included:

• Optimizing Data Structuring: Ensuring each vehicle’s data is stored separately and persistently, rather than in a single-threaded conversation.

• Enhancing Natural Language Inputs: Allowing users to add records naturally (e.g., “Log an oil change for my Jeep at Gayton Automotive on 01/20/2025 for $39.97”).

• Improving Predictive Maintenance Alerts: Factoring in not just mileage but also seasonality and historical service patterns.

3. Naming and Branding

Choosing a name that was simple, intuitive, and memorable was crucial. I started by generating 10 potential names that captured the essence of vehicle management and AI-powered assistance. Among them, one stood out: MyGarage.

Once we had the name, we refined the branding to enhance clarity and appeal. We selected the 🚗🔧 emojis to add visual recognition and condensed the name into a format that balanced brevity with impact. After several iterations, we landed on "MyGarage: Track Vehicle Maintenance & Repairs"—a name that effectively conveys its purpose while remaining concise and engaging.

Why Custom GPTs Like MyGarage Matter

Creating a custom GPT isn’t just about convenience—it’s about unlocking AI’s full potential for complex, repeat-use tasks. Instead of re-entering prompts or manually tracking vehicle records in multiple places, a custom GPT like MyGarage acts as a dedicated AI agent that grows with the user’s needs.

The Benefits of Custom GPTs for Business, Work & Life:

• Automation: Reduces manual data entry and repetitive tasks.

• Personalization: Stores and recalls user-specific details over time.

• Scalability: Works for single users or businesses managing multiple vehicles.

• Ease of Use: Allows seamless interaction through natural language input.

By designing MyGarage as a persistent vehicle record assistant, I’ve demonstrated how anyone can create their own domain-specific GPTs to streamline complex tasks—whether for cars, home maintenance, finance, or beyond.
