PARCLINES
The Founder

Hey There!

Car culture isn't the thing that holds the value — it is the value.

I built Parclines, and I'm the one who signs off on how every number here is made. I'm a lifelong car person — Southern California raised, Pacific Northwest based — who got tired of watching the market flatten every car into an average. This is who I am, why Parclines exists, and how to reach me.

01 / The story

It all cycled back to a curb in San Pedro.

I've been infatuated with vehicles for as long as I can remember. Growing up in Southern California in the late '70s and early '80s put the whole car culture in front of me early. I rode in my mom's 1961 Morgan Plus 4, and in the back seat of her best friend's new chocolate-brown 1980 Porsche 911 SC while she romped on it around a circular freeway on-ramp — and that was it. That was the car for me.

A few years later I was sitting on a curb up in San Pedro when a lowrider wedding procession rolled by, heading up to Point Fermin, and it changed my life. Candy colors with lace and ghost patterns, dingle balls, hydraulics — full-size GMs, Fords and Lincolns, and super-clean '40s bombs, all of it decorated with tissue-paper flowers stuck to the paint to mark the day. It floored me. I had to have one of each when I was old enough. I couldn't understand how I could love both worlds at once — only to learn, as I got older, there were many more I'd never even heard of.

It was in my blood. My dad came up from South Central; when his family moved to Anaheim in the early '60s he had an Anniversary Gold 1958 Impala with white tuck-and-roll, lowered, on whitewalls and chrome reverse wheels — wrecked during his Army time up in Tacoma — and then a spotless two-tone Robin's-egg-blue-and-white 1956 Buick Century. My mom was in a 1955 Chevy two-door wagon and a '57 Chevy around the same time, before they'd even met. My brothers and I never had a chance. Cars were in the DNA.

Together they ran a lot of fun cars — European roadsters and sedans, early VW Bugs, a 1967 Caprice wagon, and the ultimate SoCal family rig: a “Paddy Wagon” VW bus by Sun Dial. The bus was our daily, and eventually our moving van — a family of six and our Great Pyrenees, Harley — up to Washington State and a whole new scene. Gone were the Countachs and Porsches on PCH and the weekend lowriders; now it was muscle cars, immaculate 4x4s, and backyard builds like the Ford LTD woody wagon lifted on some unknown 4x4 frame on 33s down the street. That's where I learned car culture is unique to its region — and that the culture itself is an inherent value.

By 18 I'd already had a lot of cars pass through my hands, and I spent my college years studying cultural anthropology. The world's cultures and the way they approach life and art fascinated me — still do. It took me until my early 50s to realize that interest cycled all the way back to those first automotive experiences as a kid in Southern California. All those years of oral histories, production data, factory options, old ad magazines, buying and selling, and the arrival of online forums that finally connected car nuts across the globe and exposed entirely different regional cultures — that's what became Parclines.

What I'd realized is this: the automotive world is so vast that most of the attention and asset value pools around the blue-chips the average person can't always break into — while an entire sub-culture lives outside them, and the existing valuation tools treat all of it as an average. But a car's stories, receipts, build provenance, factory options, custom colors and wheels, engine and suspension work — that's a uniqueness that gets overlooked. I built Parclines to account for those builds, because we should all get a real reality check on our cars and our assets. The car market moves like the stock market. Not every individual choice is great for the value — but it may be fantastic for the owner, and that's what makes car culture great.

That's the line between smart and lucky.

02 / My garage

The cars that taught me — some at their own expense.

I don't value cars from a distance. Here's some of what's come through, what got away, and what I'd still chase.

…and many more.

The one that got away

The 1982 Porsche SC — it ended up going back to a dealer in Germany.

How I buy

It's impossible to identify a single market, but I approach buying cars like an investment — performing my due diligence, researching everything I can about each one, and reviewing the market first. It's the same discipline I bring to my work in procurement. Sometimes I got lucky and sometimes I got wrecked. That's part of the fun, and Parclines is designed to help potential buyers with exactly that research.

Dream specimen

My dream specimen is and will always be a fully GM-accessorized 1942 Chevrolet Special Deluxe Fleetline / Aerosedan lowrider bomb.

Biggest lesson

We all make mistakes in the game, but I would say buying a car for the wrong reason. Do your due diligence, and if you are buying to flip for the first time, do not buy what everyone else is buying, since the market is likely too hot. Do your research and search the fringe for up-and-coming deals. Talk to the old-timers in person at shows and events, get phone numbers and make human to human phone calls and connections. You will have a better chance of making the deal versus trying to make a deal over text messaging. Be willing to make the effort to meet in person and be on the level. I have had many great interactions with car folks who just want to see you respect the game and are in it for the right reason. If you blast generic offers with no backstory, be prepared for silence.

03 / The culture

The market sets a price. It never sets the worth.

These are the corners of the car world that made me care in the first place.

Lowriders & kustoms

One of my first and longest-held car passions.

Bosozoku, VIP & JDM

An amazing sub-culture that I cannot wait to see in person in Japan someday.

Vans, woodies & the strange ones

I have had a couple of vans, and they always seem to get pushed into the wrong category. Vans are amazing, and the boogie van era in particular was a blip in time that should be acknowledged and respected — and I intend to do my part to bring positive publicity to the boogie era as I can with Parclines. Woodies are a whole subculture that I have been fascinated with since I was a young kid in California. I was always told they are too drafty, too much maintenance, blah blah blah. Woodies are one of the most unique builds ever to hit the automotive world, and I do not want them to be forgotten — so one of the first things I did was create a registry of historic wood builders, as well as the small but still ongoing list of restorers. I really love the hot-rod wood surf-culture builds as well, and I know in 2026 we are finally seeing the lowrider-bomb community start restoring and building lowrider-bomb-style woodies.

Coachwork & the prewar world

The earliest car I ever owned was a 1929 Chrysler 65 Roadster, and while it was not an extremely valuable prewar car, it taught me to respect how beautiful these early examples can be. Massive chrome headlights, chrome grilles, high-design interior gauge panels — and honestly, one of the coolest things I learned was how unique the individual gauge inserts are in all of those early cars. Each one is a piece of art, all the way up to the 1942 Chrysler Bakelite gauge and dash trim panel — early design is just fascinating to me. I have never been lucky enough to own a coachbuilt car, yet, but it is the pinnacle of automotive collecting, and like the woodies I am worried the old builder information will disappear over time as car collecting changes. So I wanted to assemble the most comprehensive coachbuilder directory I could and make it readily available on Parclines for others to see and share. I made it for the old, and I also attempted to locate current and active coachbuilders worldwide to include. We must continue to respect this artform.

What I'm watching

YouTube — it is truly the quickest way to learn about new styles emerging both globally and domestically. One of my favorite influences is Larry Chen and the videos he makes about culture. He is living the dream documenting this global culture, and I could not be more stoked for him and for the industry.

Outside the garage

Architecture, design, Pendletons, classic BMX, wood-fired pizza and real bean burritos.

I couldn't fit every world in here — these are just the ones closest to me. The dune buggies, the kit cars and fiberglass specials, and the electric collectibles now coming of age all have a home on Parclines too — the full culture index maps the rest.

04 / How I work

Impounded until it's proven.

Parclines runs on a few rules I set and I keep. The engine applies them at a scale no person could — yes, it uses AI, and I won't hide the machine. But the rules are mine, and so is the accountability.

01 / Identity first

The exact car, before any price

No price until we know exactly which car it is — trim, engine, body, build. Two cars with the same badge are not the same car.

02 / Sold is not asking

Different numbers, kept apart

Realized sales, unmet high bids, and asking prices are kept separate, because they mean different things.

03 / Evidence or nothing

“Not yet priced” beats a guess

If the evidence isn't there, the car is shown as not yet priced. I'd rather say I don't know than guess.

04 / Show the work

Range, confidence, as-of date

Every value carries its range, its confidence, and the date it's based on. If you can't see the evidence, it's just an opinion.

05 / The call is yours

We report the effect, not the verdict

The numbers are ours; the call is always yours. We report how something moves value, never whether it's worth it to you.

06 / Transparency

A living site, open to data

Most importantly, with the size of the automotive market globally, I fully recognize and accept that the site may contain errors, or not even include a specific make or model — and I am ok with that. Parclines is a working site, but like all active sites, the data will continue to change and update as new data sources are captured and brought online, and as new feedback from users comes in. I have open arms for additional data, and I am even willing to offer credits when a user provides specific data the site did not capture during a valuation. The car community should be an open data exchange for the good of the entire market — that is not yet the case, and I am always looking for new data partners to work with.

What the software does: gathers, organizes and checks evidence across many sources. What I do: set the method and the evidence rules, decide what counts as a comparable, and own every correction.
