Few Mopars ignite as much passion - or start as many garage arguments - as the 1970–1974 Dodge Challenger. Born at the height of the muscle-car wars, the E-body Challenger blended Mopar attitude with a long-hood/short-deck Coke bottle profile and a factory engine lineup ranging from steady-Eddie 318s to the fire-breathing 426 Hemi V8. Today, these cars remain first-rate collectibles and prime candidates for either concours-level restorations or full blast restomods.
Both paths can lead to tire-shredding or show-stopping glory, but they take you down very different roads. Here’s a deep dive into the pros and cons of each, from cost and drivability to street cred and resale value.

- Maximum Collector Value
Originality is king in the collector market. A numbers-matching R/T or Hemi Challenger restored to factory specs commands serious money. For investors or purists, this path holds the strongest long-term financial upside. Doing some research with a Mopar VIN Decoder & Fender Tag Decoder guide comes in handy, should you be interested in restoring your Challenger.
- Historical Preservation
A proper restoration keeps Mopar history alive. You're honoring the original engineering, the craftsmanship, and the soul of the era. Judges at Mopar Nationals or MCACN eat this stuff up.
- Proven Authentic Experience
Driving a factory-correct Challenger is like hitting a time warp. The smells, the sounds, the quirks—every bit of the nostalgia is intact. It’s pure muscle-car theater.
- Parts Availability Is Better Than It Used to Be
Thanks to reproduction panels, trim, and interior pieces, restoring an E-body is far more feasible today than it was 20 years ago (thanks to companies like Classic Industries).

Cons
- Cost Can Skyrocket Quickly

- Factory Limitations Remain
Early-’70s brakes fade, suspensions flex, steering wanders, and carburetors need babying. Restoration preserves the charm and the imperfections.
- You May Be Afraid to Drive It
A six-figure numbers-matching build becomes a garage queen. Weather, traffic, and parking lots suddenly feel like mortal enemies.
- Hard to Personalize
The whole point is originality, so big wheels, modern tunes, or performance tweaks are off the table.
Restomod: The Challenger, Reinvented for the 21st Century

Drop in a Gen III Hemi. Bolt on coilovers. Add Brembo or Wilwood brakes. Upgrade to rack-and-pinion steering. You end up with a Challenger that handles like a modern Charger Hellcat but still looks like a 1970-American muscle machine.
- No Fear Behind the Wheel
Restomods are built to be driven rain or shine, highway or canyon. They’re far more livable and less precious than museum-grade restorations.
- Unlimited Creativity
Wheels, paint schemes, digital gauges, serpentine systems, EFI, custom interiors - the sky’s the limit. It’s your Challenger, your personality.
- Reliability You Can Trust
Fuel injection, modern ignition systems, and upgraded cooling make for a car that starts, runs, and drives consistently without the daily drama of vintage tech.

Cons
- Purists May Scoff
Hardcore Mopar historians will mourn the loss of originality - especially if you cut into a rare R/T or numbers-matching car.
- Costs Can Also Be Sky-High
A high-end restomod with a crate Hemi, modern chassis, and custom fabrication can easily rival the price of a top-tier restoration.
- Resale Value Is Less Predictable
While some builds bring monster money, others depend heavily on buyer taste. A restoration has a more objective standard; a restomod’s value is subjective.
- You Can't Go Back Easily
Modernizing often means irreversible changes - frame mods, wiring overhauls, custom metalwork. Once you restomod it, it’s not likely going back to stock.

Final Verdict: There’s No Wrong Answer—Only the Wrong Car for the Wrong Goal
The 1970–1974 Dodge Challenger is one of the most versatile muscle-car platforms ever made. Whether you’re resurrecting a survivor to concours glory or building a tire-shredding, fuel-injected monster, the key is choosing the path that matches your vision.

- Restomods rewrite it.
Either way, you end up with a Mopar legend that turns heads and stirs souls.
