Mach 1 Convertible: One-of-a-Kind Droptop Pony

On August 24, 2013, a large truck slammed into the back of the Mach 1, turning Sanders’s dream car into a nightmarish heap of busted glass and shredded metal. What once was a right corner instantly became a ragged stump. The driver of the pickup sped off. Sanders and his wife were lucky to walk away from the wreck.

The Mach 1 looked hideous, but its engine and transmission still worked. Instead of sending the entire carcass off to the scrapyard, Sanders paid his insurance company $1,100 for it and had it trucked to his house. A couple of years later, it was Sanders’s turn to take his car apart. He removed every salvageable component he could think of. After he picked what was left of his Mach 1 clean, he let a metal recycler haul it away.

Parts filled Sanders’s house and backyard shed; visions of a Mach 1 convertible filled his mind. I asked him what his biggest concern was about creating it largely by himself. He responded, “None really. Ford already made the Cobra convertible with the 32v motor in it since 1996.” If there was a potential problem that crossed his mind it was finding a Zinc Yellow 2003 Mustang convertible. All he wanted was the body and the color he loved; he could take care of the rest.

Sanders soon found what he was looking for. It was a garage-kept, one-owner car with a white interior and matching roof. He didn’t want to keep the seats or top, but he did like the idea of some white brightening the interior of his build, so he began another search. This time it was for some of the black and white pieces that were available in 1994-1996 Mustang convertibles. His patience soon paid off.

Just as he had done with his Mach 1, Sanders disassembled the V6 droptop. He began swapping interior parts (including the Mach 1000 audio system) into the car in September of 2015. A style bar soon followed. Despite his confidence and capabilities, he ran into challenges. Some of the interior components required retrofitting. The ribbed black and white covers Sanders had ordered were difficult to fit on the front seats. Instead of going through the trouble of installing a new black soft top, he had a shop do it. Sanders bought a Roush rear wing to cap off the trunk lid.

Underneath, Sanders equipped Machenstein with beefed-up upper and lower rear control arms, full-length subframe connectors, motor and transmission mounts, and a K-member kit consisting of the K-member itself, lower control arms, camber and caster plates, a coilover package, and hardware for repositioning the front sway bar. A set of staggered-width wheels and tires (17″ X 8″ and 245/45/17 rubber in the front and 17″ X 10.5″ and 335/35/17 rubber in the back) connect Machenstein to the road.

By September of 2016, Sanders was ready to put the Mach 1’s long-dormant heart into its new body. Before he lowered the 4.6 into the engine bay, he added underdrive pulleys. That entire procedure was problem-free. Sanders said his biggest challenge was “lining up the upper and lower control arms bolt holes, with the holes on the chassis while the control arms were mounted to the differential.” He enhanced that inside and out by filling it with 4.10 gears and protecting it with a finned cover that helps the diff cool. Everything was more or less in place by November.

“At times it was frustrating and other times it was a big sense of accomplishment, especially the day I started up the engine for the first time and there were no error codes, just the blissful sound of a 4 cam engine running,” Sanders said.

It’s only a matter of time until Sanders’s Mach 1 comes apart again. When it does, it’ll be on his terms. He’s thinking about pulling out Machenstein’s engine, upgrading its bottom end, and installing a ProCharger.

Derek Shiekhi's father raised him on cars. As a boy, Derek accompanied his dad as he bought classics such as post-WWII GM trucks and early Ford Mustang convertibles.

After loving cars for years and getting a bachelor's degree in Business Management, Derek decided to get an associate degree in journalism. His networking put him in contact with the editor of the Austin-American Statesman newspaper, who hired him to write freelance about automotive culture and events in Austin, Texas in 2013. One particular story led to him getting a certificate for learning the foundations of road racing.

While watching TV with his parents one fateful evening, he saw a commercial that changed his life. In it, Jeep touted the Wrangler as the Texas Auto Writers Association's "SUV of Texas." Derek knew he had to join the organization if he was going to advance as an automotive writer. He joined the Texas Auto Writers Association (TAWA) in 2014 and was fortunate to meet several nice people who connected him to the representatives of several automakers and the people who could give him access to press vehicles (the first one he ever got the keys to was a Lexus LX 570). He's now a regular at TAWA's two main events: the Texas Auto Roundup in the spring and the Texas Truck Rodeo in the fall.

Over the past several years, Derek has learned how to drive off-road in various four-wheel-drive SUVs (he even camped out for two nights in a Land Rover), and driven around various tracks in hot hatches, muscle cars, and exotics. Several of his pieces, including his article about the 2015 Ford F-150 being crowned TAWA's 2014 "Truck of Texas" and his review of the Alfa Romeo 4C Spider, have won awards in TAWA's annual Excellence in Craft Competition. Last year, his JK Forum profile of Wagonmaster, a business that restores Jeep Wagoneers, won prizes in TAWA’s signature writing contest and its pickup- and SUV-focused Texas Truck Invitational.

In addition to writing for a variety of Internet Brands sites, including JK Forum, H-D Forums, The Mustang Source, Mustang Forums, LS1Tech, HondaTech, Jaguar Forums, YotaTech, and Ford Truck Enthusiasts. Derek also started There Will Be Cars on Instagram, Facebook, and YouTube.
