Titling a Kit Car or Assembled Vehicle in Michigan

Determine whether the build is assembled

The Secretary of State's assembled-vehicle instructions cover vehicles built from parts by someone who is not a recognized manufacturer, substantially altered original vehicles, certain body substitutions and road-use kits. The construction history determines the process. A recognizable donor chassis does not necessarily make the finished vehicle an ordinary example of the donor model.

Describe the planned body, frame, drivetrain and intended road use to the Secretary of State before purchasing expensive components. Bring photographs and the kit manufacturer's paperwork if classification is uncertain. A seller's description such as replica or custom does not establish which Michigan title procedure applies to the completed machine.

Distinguish an assembled title from a salvage rebuild

Michigan's title categories separate assembled vehicles from damaged vehicles restored under salvage procedures. Repairing an existing salvage vehicle generally follows its branded ownership record. Creating a substantially different vehicle from documented components may raise assembled-vehicle questions instead. Explain both the donor history and the actual construction work.

The applicable ownership evidence remains important even if nearly every mechanical part has been replaced. Keep donor titles and any salvage or scrap markings visible in the file. Do not discard a restrictive certificate because a seller says the project can simply receive a new identity after inspection.

Preserve ownership evidence as parts arrive

The assembled instructions identify major components that must be accounted for, including the engine, transmission, body parts, frame with axles and wheels for a motor vehicle. Michigan's ownership information is useful when acquiring a complete donor, since a purchase invoice and a transferable title serve different purposes.

For each component purchase, retain the buyer or builder's name and address, purchase date, description, amount paid, serial numbers when present, and the supplier's contact information. Record engine, transmission and frame numbers while they remain accessible. Match the receipt to the physical component before paint, upholstery or fabrication conceals identifying marks.

Maintain a construction record that follows the vehicle

A practical build file should connect each major component to its supporting document and show how it became part of the finished vehicle. Keep kit instructions, manufacturer certificates, donor ownership records and purchase receipts together. Photograph the project at useful stages, especially when a later inspection cannot easily reveal the source of a frame or body section.

Use the official form library for application materials rather than adapting another state's assembled-vehicle forms. At the Michigan office, the owner completes a certification describing construction. A contemporaneous record makes that explanation more accurate than reconstructing the sequence from memory after the vehicle is complete.

Handle scrap components under their separate restrictions

The instructions permit certain scrap-derived components only under specific dismantling and combination rules. The scrap vehicle must be completely dismantled before its frame or unitized structure is reused; the assembled vehicle must incorporate major components from multiple vehicles. It cannot combine a scrap donor's frame or unitized structure with another major component from that same donor.

Review Michigan's salvage and scrap statute before choosing a damaged donor. A scrap certificate is not permission to restore the original vehicle for road use. Maintain documents showing the source and separate identity of each qualifying component instead of treating a cosmetic rebuild as a new assembly.

Plan the Michigan police equipment inspection

The TR-54 Vehicle Number and On-Road Equipment Inspection is completed by a Michigan police officer for the required serial-number and equipment review. The assembled instructions call for completion of the relevant identification and equipment portions. Arrange the visit with an agency that can perform this particular inspection.

Review the equipment checklist while building so the officer can inspect a finished, accessible vehicle. An inspection appointment is not an authorization for unrestricted operation beforehand. Explain how the vehicle will reach the inspection site and confirm that any narrow statutory movement provision fits the actual trip rather than assuming a test drive qualifies.

Understand what the inspection does and does not replace

Michigan has no general annual safety or emissions inspection for ordinary passenger vehicles. That does not remove the specific equipment examination required for an assembled title. The registration statute describes limited movements for weighing and law enforcement inspection; those exceptions should be read according to their stated purpose.

A completed TR-54 also does not waive federal requirements that apply to imported kits, engines or equipment. The EPA kit-car policy addresses emissions treatment, while NHTSA's import explanations distinguish vehicles from equipment assemblages. Resolve federal entry questions before ordering an overseas project.

Add category-specific evidence for motorcycles and trailers

An assembled motorcycle has its own component list, including the engine, transmission, frame, front-end assembly, wheels and seat. Account for those items directly rather than submitting a car-oriented inventory with irrelevant blanks. Its insurance and operator requirements also differ from those of a passenger car once the project is approved for road use.

An assembled trailer or trailer coach needs a weight slip under the state instructions. Michigan's recreational vehicle guidance explains trailer titling and permanent plates. Document the frame, axle, wheels and applicable box or body unit. Ask the weighing location how to obtain an appropriate empty-weight receipt before moving the trailer.

Submit the application and budget for the assigned VIN

Present the ownership documents, construction certification, completed inspection and any necessary weight evidence at a Secretary of State office. The assembled instructions list a $10 charge for the new VIN sticker and an estimated 8-10 weeks for processing the title and special identification number (read October 21, 2026). That estimate depends on a complete, acceptable submission.

The title and registration service explains associated title, tax and registration transactions. Ask the clerk to distinguish those charges from the VIN fee. Bring evidence of taxes already paid on acquisitions so the office can evaluate the applicable tax treatment instead of guessing from the total construction budget.

Wait for the arranged VIN installation

During assembled-title processing, the state's instructions do not allow a license plate or temporary permit for the project. Supply a telephone number where the office can reach you about the next stage. Continue storing and transporting the vehicle according to its actual status while the title and assigned number are researched.

After processing, the owner is contacted to arrange presentation at a designated location. The vehicle is examined again and the special VIN sticker is installed. The title application statute provides the broader ownership framework; the state-issued identification should remain intact and correspond with the resulting certificate.

Arrange coverage and plates for the completed vehicle

Discuss the assembled classification, component value and intended use with an insurer before the vehicle is ready for registration. Michigan's PIP medical coverage guidance helps a passenger-car owner evaluate policy choices. The insurer may also need photographs, an appraisal or details about modifications to quote physical-damage coverage accurately.

Once the title and VIN stage is completed, purchase or transfer the appropriate plate with the required insurance. Use the plate-transfer instructions if reusing an eligible plate. Retain the build evidence after registration; it remains useful when insuring, repairing, valuing or selling a vehicle that differs from a standard production model.

Resolve an incomplete submission before adding paperwork

If the office requests more evidence, identify the specific component or transaction that remains unsupported. A missing donor assignment, an incomplete inspector section and a question about construction classification require different responses. Provide the original source document or a clear correction from the appropriate person instead of submitting an unrelated receipt because its value seems similar.

Keep a copy of the office's request with the pending application receipt. Label the additional documents so their connection to the identified vehicle is apparent. Contact the office about delivery and whether another appearance is necessary, especially if the project is difficult to transport. This approach helps preserve one coherent application record through review and eventual VIN installation.

Frequently Asked Questions

Can a Michigan kit car simply use the donor vehicle's title?
The finished configuration determines the correct title process. Substantial changes or construction from multiple components can require assembled treatment even when one donor supplies the frame.

Which person completes the assembled vehicle's TR-54?
A Michigan police officer performs the required identification and equipment review. Contact the agency in advance to arrange that inspection and appropriate presentation of the vehicle.

May I obtain a temporary plate while Michigan researches my assembled title?
The assembled instructions prohibit a plate or temporary permit during that processing stage. Arrange storage and suitable transport until the state completes the required sequence.

Does a kit manufacturer's invoice document every part of my build?
It documents what the manufacturer actually supplied. Separately acquired engines, transmissions, frames and other required components need their own ownership evidence.

Can components from a scrap-titled vehicle be used without restrictions?
Scrap-derived assemblies must meet the dismantling and component-combination rules. Rebuilding the original scrap vehicle does not make it eligible for ordinary road registration.

Will Michigan accept my homemade trailer's estimated weight?
The assembled instructions require a weight slip for a trailer or trailer coach. Obtain the actual scale documentation and bring it with the component records.
