Assembly - Project Car Hub

Assembly gives every project car a home. Plan projects, track parts, and centralize all of your plans, photos, files, checklists and notes in one shareable place.

Assembly is the home for project cars. Plan projects, track parts, document modifications, organize maintenance, and keep a complete history for every vehicle in your garage.

Keep every part, project, note, photo, receipt, file, and update connected to the car it belongs to—so months or years from now, you'll still know exactly what you changed, why you changed it, and what comes next.

Whether you're planning an engine swap, documenting a restoration, organizing maintenance, fabricating custom parts, or simply trying to remember which part you installed three years ago, Assembly helps you keep the entire story together.

Most project cars are managed across notes apps, spreadsheets, photo libraries, receipts, forum posts, and memory. Assembly brings everything together in one place designed specifically for enthusiasts who modify, restore, maintain, fabricate, and continually improve their own cars.

Features

PLAN PROJECTS Keep plans, research, notes, photos, tasks, and parts together from start to finish. Assembly was designed for complex, long-term projects that evolve over months and years—not just routine maintenance. Whether you're restoring a classic, fabricating custom parts, building an engine, or developing a track car, Assembly grows with the project.

TRACK PARTS AND MODIFICATIONS Organize parts you need to buy, parts waiting to install, and parts already installed. Record part numbers, costs, purchase links, installation dates, mileage, receipts, and notes to create a complete history of your car.

CENTRALIZE YOUR DOCUMENTATION Instead of scattering information across notes, checklists, spreadsheets, emails, and photos, keep every modification, maintenance record, specification, and document attached to the vehicle itself. Always know the current state of your project car.

STORE PROJECT FILES Upload wiring diagrams, CAD files, receipts, manuals, PDFs, and other files related to your projects. Storage limits depend on your selected plan.

CONNECT WITH OTHER ENTHUSIASTS Follow people working on similar project cars. Browse project updates, photos, documentation, specifications, and community discussions. Share your progress, learn from real project histories, and help others tackle similar challenges. For enthusiasts who still love the classic forum experience, Assembly also preserves a searchable project history that feels more useful than a traditional build thread.
