What We Do

Real work.
No shortcuts.

Whether it's a 60s muscle car or a daily driver that's been giving you trouble — we've got the know-how.

Wiring & Electrical

Custom harnesses, diagnostics, repairs — we speak wire. From vintage ignition systems to modern ECUs, your electrical gremlins won't stand a chance.

Engine Performance

Tuning, rebuilding, swapping — flatheads, V8s, turbos, naturally aspirated. We pull power the right way: measured, tested, and reliable.

Brakes & Suspension

Stopping power and ride quality matter. We install and service brakes, shocks, coilovers, and everything that connects your tires to the road.

Diagnostics

Check engine light on? Car's running rough? We use proper scan tools and old-school intuition to figure out what's actually wrong — not just throw parts at it.

General Maintenance

Oil changes, fluid flushes, belt replacements, tune-ups — the stuff that keeps your car running smooth and your wallet from getting wrecked later.

Custom Builds

Got a project in mind? Rat rod, restomod, show car, track weapon — we love a good build from the ground up. Let's talk vision.

About Us

We don't just fix cars —
we understand them.

Paul's Vintage Wiring and Speed Services started as a one-car garage dream in Dacono and grew into the go-to shop for anyone who wants honest, competent work on their vehicle.

We specialize in the stuff other places gloss over: electrical gremlins, custom wiring, performance tuning that actually moves the needle. But we also handle the everyday stuff — brakes, oil changes, general maintenance — with the same care we'd give our own ride.

Every car that rolls into our bay gets treated like it matters. Because it does. Whether it's your daily driver, your weekend project, or the car you've been meaning to get started on for three years — we're here for it.

Kind Words

What folks are saying

"Brought my '67 Mustang in with an electrical nightmare that two other shops couldn't sort out. Paul diagnosed it in an hour and had it running perfect by the next day. Absolute wizard with a multimeter."

"Finally found a shop that doesn't talk over my head or upsell me stuff I don't need. Paul explains everything in plain English and the prices are fair. My go-to for everything now."

Sarah L.

Lafayette, CO

"Had a custom wiring job done on my Fox Body and the harness looks factory-better. Clean, labeled, and the car starts on the first crank now — something it hadn't done in years. Thank you, Paul!"
