The short answer
Where the money goes in a 12-stage build
Cost drivers are described qualitatively; the exact allocation depends on specification. Confirm current ranges on the pricing page.
Why publish the full 12-stage breakdown
Most custom Defender builders describe their process in broad strokes. Monarch Defender publishes the full 12-stage sequence because a commission at this price deserves transparency: you should know exactly what happens to the vehicle, in what order, and where the money goes.
Every Monarch build follows the same 12 stages at the facility in Grayslake, Illinois. The vehicle is built ground-up on a new KTL-coated chassis from a Monarch-sourced donor; customer cars are not restored, though trade-in credit is accepted.
Stages 1 to 4: what builds the foundation?
The first third of the build creates the structure everything else depends on. This is where corrosion protection and panel quality are locked in.
- Stage 1, Donor Selection: Monarch sources and inspects the donor vehicle itself, so the starting point is known and consistent.
- Stage 2, Chassis Restoration: the build moves onto a new KTL-coated chassis, protecting the structure against corrosion for the long term.
- Stage 3, Body & Panel Work: panels are restored, aligned, and prepared so gaps and surfaces meet modern standards.
- Stage 4, Premium Paint: a multi-layer, show-quality paint system is applied in the owner's chosen color.
Stages 5 to 8: what makes it comfortable and personal?
The middle stages turn a painted shell into a personalized vehicle. This is where most of the bespoke decisions land.
- Stage 5, Insulation & Comfort: thermal and acoustic insulation bring cabin refinement closer to a modern vehicle.
- Stage 6, Modern Electronics: an all-new wiring harness and integrated safety technology replace the aging original electrics.
- Stage 7, Bespoke Interior: custom leather and hand-finished trim, built to the owner's specification.
- Stage 8, Custom Accessories: functional and aesthetic additions specified by the owner, giving each build its character.
Stages 9 to 12: what makes it drive like a modern truck?
The final third installs the drivetrain, proves the vehicle, and delivers it.
- Stage 9, Performance Powertrain: the GM LS3 V8 (about 430 hp) or LT1 V8 (about 460 hp), a modern automatic transmission, and upgraded axles, suspension, and brakes.
- Stage 10, Connected Tech: modern infotainment and wireless convenience features integrated into the classic cabin.
- Stage 11, Rigorous Testing: a comprehensive performance and quality-assurance protocol before the vehicle is signed off.
- Stage 12, Final Delivery: final detailing, then white-glove delivery in the US or managed worldwide shipping.
Which stages drive the cost?
Three areas account for most of a build's cost: the body and paint work, the bespoke interior, and the modern V8 powertrain. Body and paint are labor-intensive because panel work and a multi-layer finish cannot be rushed. The interior is made to one owner's specification, which is skilled-labor work by definition. The powertrain stage covers the V8, transmission, axles, suspension, and brakes as a complete modern driveline.
The remaining stages matter less to the invoice but just as much to the result. Insulation, electronics, and testing are where a build earns daily usability. Monarch does not price stages individually; the specification as a whole determines where a build lands in the $250,000 to $350,000 and up range.
Frequently Asked Questions
What are the 12 stages of a Monarch Defender build?
Donor Selection, Chassis Restoration, Body & Panel Work, Premium Paint, Insulation & Comfort, Modern Electronics, Bespoke Interior, Custom Accessories, Performance Powertrain, Connected Tech, Rigorous Testing, and Final Delivery. Every build follows the same sequence at Monarch's facility in Grayslake, Illinois.
Which part of a custom Defender build costs the most?
Qualitatively, three areas dominate: body and paint work, the bespoke interior, and the modern V8 powertrain with its transmission, axles, suspension, and brakes. Exact allocation depends on specification, which is why builders quote a build as a whole rather than per stage.
Can I follow my build through the stages?
Yes. Monarch documents the build as it moves through the stages, so you can see the vehicle progress from donor and chassis through paint, interior, and powertrain rather than waiting blind for a delivery date.
Does Monarch restore my existing Defender through this process?
No. Every Monarch vehicle is built ground-up from a Monarch-sourced donor on a new KTL-coated chassis; customer restorations are not offered. A current Defender can be applied as trade-in credit toward a new build instead.
How long do the 12 stages take?
A Monarch commission typically takes 6 to 12 months from committed order to delivery, depending on specification complexity. Payments are structured as a deposit plus milestone progress payments tied to the build stages.
