Out of all the classics I get calls about, the Mustang is the one that keeps showing up. My name is Sonny Miller, I have been buying classic cars across Southern California for over 20 years, and Mustangs from the ’60s and early ’70s are still hiding in garages from Long Beach to Van Nuys.
Usually it is not even the original owner calling. It is a son, a daughter, a widow, somebody who inherited a car and a lot of questions. If that is you, call me at (714) 900-3723. You are calling a classic Mustang buyer, not a call center. I pick up personally, the quote is free, and I will tell you what you actually have before we ever talk money.

How a Mustang Deal Goes Down With Me
You call, you tell me the year, the body style, and the fifth digit of the VIN. That is it. I will tell you on the phone what that combination means and give you a real number. If it works for you, I come out the same day in most cases, anywhere from Los Angeles County to Orange County and beyond. Cash, Zelle, Cash App, check, or wire.
The paperwork happens at your curb, even if you lost the title years ago. And if the car does not run, the tow truck is on me. You do not push a Mustang anywhere.
1964½ to 1966: The Cars That Started It All
The Mustang went on sale April 17, 1964, built on Ford Falcon bones, and the earliest cars are titled as 1965s. Collectors call them 1964½ cars. The fastback did not arrive until August of 1964, and that matters, because hardtop coupes outsold everything else close to five to one. In 1966 only about 35,000 fastbacks were built. That scarcity is exactly why a fastback brings serious money over a coupe today.
When one of these calls comes in, the first thing I ask about is the door data plate. It tells me the body style, the original color, the trim, and the build date. Original drivetrain and original paint add money, even tired original paint. And the K-code 289 Hi-Po, 271 horsepower from the factory, is the one every early Mustang owner hopes they have.
1967 to 1968: Big Blocks Arrive, and So Does the California Special
Ford grew the car in 1967 for one main reason, fitting the 390 big block. You can spot a ’67 by its concave tail panel, and it was the last year for the K-code. Then in April of 1968 the 428 Cobra Jet showed up mid-year and changed the whole conversation.
Here is the one close to home. The 1968 GT/CS, the California Special, came out of a California Ford dealer promotion. Just 4,118 were made, with Shelby-style tails and side scoops. Plenty went out of state, and 251 of them became Denver High Country Specials, but California is where most of them landed. Which means they are still sitting in garages right here. If somebody in your family bought a special looking Mustang in Anaheim in 1968, look twice at it before you call anyone.
1969 to 1973: Mach 1, Boss, and the Last of the Classics
In 1969 the fastback became the SportsRoof and the lineup exploded. The Mach 1 arrived with a 351 standard and the 428 Cobra Jet on the option sheet. The Boss 302 existed so Ford could go Trans-Am racing, 1,628 built in ’69 and 7,013 in ’70. The Boss 429 existed for NASCAR, only 859 and then 499. Production numbers like that are why real Boss cars bring six figures.
The ’71 to ’73 cars grew about 8 inches longer and 6 inches wider than a ’65. For years they were the affordable way into a classic Mustang, and the market has been kinder to them lately. The classic era ends there. The 1974 Mustang II moved onto Pinto bones with an 88 horsepower four cylinder and no V8 at launch. I still buy them, but the money is a different conversation, and I will be honest with you about it.
The Special Models and Why They Bring Money
| Model | Years | Why It Brings Money |
|---|---|---|
| K-code 289 Hi-Po | 1964½ to 1967 | 271 hp factory Hi-Po, the holy grail small block |
| Shelby GT350 | 1965 to 1969 | Shelby-built fastbacks, ’65 and ’66 cars bring the most |
| Shelby GT500 | 1967 to 1970 | 428 power, big auction money |
| GT/CS California Special | 1968 | Only 4,118 built, sold through SoCal dealers |
| Mach 1 | 1969 to 1973 | SportsRoof performance package, 428 Cobra Jet cars on top |
| Boss 302 | 1969 to 1970 | Trans-Am homologation car, 8,641 total |
| Boss 429 | 1969 to 1970 | NASCAR engine in a Mustang, about 1,358 total |
| Grande | 1969 to 1973 | Luxury hardtop trim, the sleeper of the bunch |
The Fifth Digit of Your VIN Is Worth Real Money
My favorite phone calls are the ones where I ask for the fifth character of the VIN and the seller goes quiet for a second, walks out to the garage, and reads me a letter that changes their whole week. That fifth character is the engine the car was born with. K means the 289 Hi-Po. A means the 4-barrel 289. C means the 2-barrel. One letter can move the price by thousands before I ever see the car.
Then check the door data plate, because that is how clones get caught. A real 1969 Mach 1 carries body code 63C. A regular SportsRoof is 63A. Anybody can add stripes and a hood scoop. Nobody can change the plate. Matching numbers means the engine and transmission stampings tie back to this exact car, and sellers use that term loosely, so I verify it at the car.
For 1967 and newer, a >Marti Report pulls Ford’s own production records and shows exactly how your car left the factory, engine, color, options, all of it. There is no Marti data for ’65 and ’66, so on the early cars the data plate and the stampings do the talking. If you have a Marti Report in the glove box, tell me on the phone. It adds real money.
What Classic Mustangs Are Bringing in 2026
Numbers move around, but here is what >the market trackers show as of mid-2026. Take these as ballparks. Condition swings everything, which is exactly why I quote every car individually instead of off a chart.
| What You Have | What the Market Shows |
|---|---|
| ’65 to ’66 coupe, driver condition | Roughly $17,000 to $45,000 asking |
| ’65 to ’66 fastback | Around $52,000 benchmark, projects from about $8,000 |
| ’69 to ’70 Mach 1 | Around $73,000 benchmark, 428 CJ cars $85,000 and up |
| ’67 to ’68 Shelby GT500 | Recent sales averaging near $193,000 |
| ’65 to ’66 Shelby GT350 | Benchmarks in the $340,000 range |
And before you write off the rough one in the driveway, an $8,000 project fastback is still real money for a car that has not turned a wheel since the ’90s.

What I Check in the First Five Minutes
Every serious Mustang buyer in the country checks the same spots, so you might as well know them before anyone shows up. The cowl vent under the windshield is the famous one. Water gets in there, sits, and rots the cowl from the inside, then leaks onto your floorboards. Pour a cup of water down the cowl and watch where it comes out. That test has ended a lot of arguments.
After that it is torque boxes, shock towers, frame rails, floor pans under the carpet, and the trunk floor. A magnet tells me whether a quarter panel is metal or filler. None of this scares me away, by the way. Rust just belongs in the number, and an honest number up front beats a surprise at the end.
Been Sitting Since the ’90s? Do Not Restore It First
I mean this. Restoration almost always costs more than it adds, and the market has moved toward honest, original survivor cars. Do not repaint it, do not swap the interior, do not even give it a heavy detail. The story of an untouched car is worth money, dust included.

The story is usually the same one. Dad bought it, Dad always meant to fix it, and now the family needs the garage back. The tires went flat somewhere around the second Bush administration, there are boxes on the hood, and nobody can find the title. I buy Mustangs in exactly that condition, the paperwork gets squared away at pickup, even after years on non-op.
Quick Answers on Selling a Classic Mustang
When You Should Not Sell to Me
I will say this plainly, because it is the truth and you will find it out anyway. I buy to resell, so I have to make something on the deal. If you have a documented Boss 429, a real Shelby, or a numbers-matching Mach 1 with a Marti Report in the folder, your money is at a collector auction, not with me. Call me anyway and I will tell you that, and I will tell you who to call.
Where I win is everything else. The coupe with a rusty cowl. The fastback that has not run since 1998. The car that came with the house. The one where the private party buyers keep asking to see it and never show up. I bring cash, I bring a tow truck, and I bring the paperwork. That trade, speed and certainty for a fair number, is the whole business. It is the same way I buy every classic car in Southern California.
Ready to Find Out What Your Mustang Is Worth?
Grab the VIN, look at that fifth digit, and call me up. I answer personally, I am a Southern California resident, not a corporate robot, and if your car belongs at a collector auction instead of a cash sale, I will tell you that too and point you in the right direction. One Mustang or a barn full. Finding a classic Mustang buyer who answers his own phone should not be the hard part of this. And if there are other Fords sitting next to it, I buy those too.
