Ever dream of cruising through Colorado’s mountain roads in a car you built yourself? Maybe you’re picturing a classic Cobra replica, a dune buggy for the dunes, or a futuristic electric hot rod. Building a kit car in Colorado isn’t just for gearheads—it’s a project that anyone with patience (and a love of tinkering) can tackle. But before you hit the road, you’ll need to follow some important state rules. Colorado has its own way of handling kit cars, and if you don’t want your project gathering dust in the garage, you’ll want to get it right.
What’s a Kit Car (According to Colorado)?
In Colorado, a kit car is usually called a “Specially Constructed Vehicle” or “Reconstructed Vehicle.” This means any car you built from a kit, a bunch of different parts, or by majorly rebuilding a donor vehicle. If your car didn’t roll out of the factory the way it looks now, you’re in kit car territory.
This includes everything from a fiberglass-bodied hot rod to a street-legal sand rail or home-built electric buggy.
Why Are There So Many Rules?
It’s not just to make life harder (promise!). Colorado wants to make sure every car is safe, traceable, and not stolen. The state also wants you—and everyone else on the road—to be protected if there’s ever an accident or problem.
Step 1: Save Every Scrap of Paper
Organization is your best friend. Colorado’s DMV and State Patrol will want to see:
- Receipts for every major part—chassis, body, engine, transmission, axles, etc.
- Title for donor vehicles or frames (signed over to you)
- Manufacturer’s Certificate of Origin (MCO) if you bought a new kit
- Your driver’s license or Colorado ID
- Build photos—not required, but super helpful for inspections
If you don’t have a paper trail for a major part, the state might make you jump through extra hoops—or say no entirely.
Step 2: VIN Assignment and Inspection
Your kit car needs a legal Vehicle Identification Number (VIN). If you’re building on a new chassis or parts from multiple sources, Colorado will assign a new state VIN.
Here’s what you’ll do:
- Complete your build (the car should be driveable, even if it’s not pretty yet!)
- Make an appointment with the Colorado State Patrol for a VIN inspection
- Bring all your paperwork, parts receipts, and the car itself
The officer will inspect your car, compare the parts and paperwork, and assign a Colorado VIN plate if everything matches up.
Step 3: Emissions—Yes, You Might Need a Smog Test
Colorado requires emissions testing in certain counties (like Denver Metro, Boulder, and parts of Weld County). If you live outside these areas, you might be off the hook. But if you’re in an emissions area:
- Your kit car will be tested based on the year of the engine, not the body style
- If you have a brand-new or electric engine, you may get special rules or even exemptions
Always check with your local DMV or Air Care Colorado for the latest requirements.
Step 4: Safety Inspection—Keeping Things Safe on the Road
The VIN inspection usually doubles as a safety check, but Colorado expects every vehicle to meet basic safety standards:
- Working headlights, taillights, and blinkers
- Brakes and tires in good shape
- Windshield (safety glass) and wipers
- Seat belts (required for all seating positions)
- Mirrors, horn, and other basics
If you miss a safety item, you’ll fail inspection and have to fix it before trying again.
Step 5: Title and Registration—Making It Official
Once you’ve got your VIN and passed inspection, you’ll visit your county DMV to apply for a Colorado title as a “specially constructed” or “reconstructed” vehicle. Bring all paperwork, your new VIN, inspection report, and proof of insurance.
Pay your title and registration fees, and you’ll get Colorado license plates—sometimes even custom or collector plates if your kit car is a replica or a historic build.
Step 6: Insurance—Don’t Skip This Part
Colorado law requires insurance for every vehicle on the road, and that includes your kit car. Not every insurance company knows what to do with a custom ride, so look for companies that specialize in classic, kit, or custom vehicles. They’ll probably want:
- Photos of your finished car
- An appraisal (for value)
- All your paperwork and VIN
Insurance protects you and your investment, and it’s the last thing you want to skip.
Common Kit Car Mistakes in Colorado
- Missing receipts for big-ticket parts
- Not getting a VIN inspection (required for all special builds)
- Assuming emissions rules don’t apply—check your county!
- Forgetting basic safety items (mirrors, horn, seat belts, etc.)
- Trying to register as a “regular” car—always use “specially constructed” or “reconstructed” on the forms
Kit Car Community in Colorado
Colorado has a big car culture, from street rods in Denver to dune buggies in the sand dunes. Local clubs, car shows, and online groups are great places to ask questions, share your progress, and get advice from people who’ve already survived the DMV maze.
Expect to get questions everywhere you drive your kit car, from gas stations to the grocery store. Most people are just curious (and maybe a little jealous!).
Colorado Kit Car FAQs
- Can I drive my kit car every day? Sure—if it’s street legal, insured, and registered.
- Do I need emissions testing everywhere? Only in certain counties. Rural areas are usually exempt.
- Can I register a kit car from another state? Yes, but you’ll need a Colorado VIN inspection and to follow the local process.
- How long does the process take? Depends—anywhere from a couple weeks to a couple months if paperwork or inspections are slow.
Ready to Roll?
Building and registering a kit car in Colorado takes time and patience, but it’s worth every minute when you finally take your creation out on those scenic roads. Stay organized, ask lots of questions, and don’t cut corners on safety or paperwork. When you roll through a Colorado mountain pass in your own custom ride, you’ll know the work paid off.
Good luck, have fun, and wave when you see another kit car on the road—you’re part of a pretty cool club now!
