What It’s Worth Right Now
If you’re wondering what these wild Mustangs go for, Classic.com pegs the average value for modified ‘69-‘70s at just over $96,000, with a high-water mark around $99,000. That’s across 162 sales in the last 13 years, with 13 more currently up for grabs. Of course, these numbers are all over the map, since every custom build is its own animal.
Zoom in a bit, and the numbers get even wilder: a smaller sample averages $106,000, but prices swing from $31,900 all the way up to a jaw-dropping $346,500. It all comes down to how well the car’s been built, what’s under the hood, and whether the paperwork checks out.

Right now, $50,000 is a bargain compared to those averages, but the auction isn’t over yet. The 427 and stick shift are big draws, but don’t forget: this is a custom build, and there’s a mismatch between the VIN and the warranty tag. The hammer price will come down to how much bidders want it—and what a close inspection turns up.
Condition and Details
This Mustang struts around in bright green with black stripes, a hood scoop, LED headlights, dual racing mirrors, Sport Slats, and a rear spoiler for good measure. It rolls on 17-inch American Racing VN 427 wheels wrapped in Toyos. One note: the driver’s door was swapped out during the refresh.

Under the hood, you’ll find a Ford Performance 427 crate V8, fed by Holley Sniper fuel injection and sparked by MSD ignition. Ceramic-coated headers and a shiny CVF serpentine setup round out the look. Cooling? That’s handled by a three-core aluminum radiator and twin electric fans. Power goes through a Tremec five-speed and a Ford 9-inch rear with 3.91 gears and a Traction-Lok diff. The engine’s a 2012 build, but the listing keeps its actual output a mystery.

The chassis gets the full treatment: Mustang II-style front suspension with adjustable coilovers, tubular control arms, power rack-and-pinion steering, Wilwood discs up front, and drums out back. Scott Drake leaf springs, sway bars front and rear, and subframe connectors keep things tight. Inside, you get black vinyl seats with green accents, a Shelby-style wheel, digital gauges, Vintage Air, and Bluetooth tunes. It’s titled as a 1970 Mach 1, but heads up – the warranty tag doesn’t match the VIN, so double-check the paperwork before you get too excited.

What Makes the 1970 Ford Mustang SportsRoof Unique
The ‘69-‘70 Mustangs went bigger and bolder, and the SportsRoof’s swooping roofline is still a favorite among Mustang diehards. This one cranks up the attitude with modern wheels, loud paint, black stripes, and a rear spoiler, but keeps that unmistakable fastback shape.

Bring a Trailer
The 427 crate V8 and five-speed manual put this car in a different league from your average Mustang. With fuel injection, modern cooling, reworked suspension, and sharper steering and brakes, this is pure restomod territory – not a numbers-matching restoration. Whether it’s a winner comes down to how well it’s been built and whether the paperwork backs it up.
Final Thoughts
At $50,000, this Mustang is a tempting alternative to the sky-high prices some custom builds command. The V8, stick shift, and upgraded chassis make it a solid pick if you want classic fastback looks with modern muscle underneath.
Thinking of bidding? Get a pro to check it out, make sure the VIN and warranty tag story adds up, and take a close look at the engine and drivetrain install. Don’t forget to eyeball the bodywork, suspension, brakes, and fuel injection, too. These steps will tell you if the price matches the build quality.
