Restorations
& Custom Builds

One of the first questions any new classic muscle car buyer faces is not which car to buy, but what kind of car to buy. A numbers-matching restored original, a restomod with selective modern upgrades, or a full pro-touring build with contemporary mechanicals under a period-correct body – these are fundamentally different ownership experiences at fundamentally different price points, and choosing the wrong one for your situation is an expensive mistake. This guide explains what each category means, what it costs, who it suits, and what to watch out for when evaluating any example on the market.

At Pedal to the Metal, we sell all three types and build the latter two at our restoration facility in the Netherlands. These distinctions come up in almost every conversation we have with buyers.

A numbers-matching restored car is one where the major drivetrain components – primarily the engine block and transmission – carry factory-stamped codes that match the car’s original build documentation. The car has been returned to its factory specification through restoration work, but the core identity of the vehicle, meaning the specific engine it left the factory with, remains intact. For serious collectors and investors, numbers-matching is the standard that commands the highest values and provides the strongest long-term appreciation. A numbers-matching 1969 Camaro Z/28 or a 1970 Hemi Cuda is a fundamentally different asset from an identical-looking car with a replacement engine, and the market prices them accordingly.

Prices vary enormously by model, year, and specification. As a general range across the models Pedal to the Metal works with most often, expect to pay between €55,000 and €85,000 ($60,000 to $90,000) for a well-restored driver-quality first-generation Mustang or Camaro hardtop with a desirable small-block engine. High-performance variants with documented matching numbers – a Z/28, an SS 454, a Challenger R/T with the 440 – typically start from €90,000 ($100,000) and climb well above €180,000 ($200,000) for the best examples. Hemi-powered Mopars and documented Shelby or COPO cars occupy a different tier entirely, with values starting above €180,000 ($200,000) and reaching into the millions for the rarest configurations.

A restomod, short for restoration modification, keeps the original body, interior, and visual character of a classic muscle car while selectively upgrading specific mechanical systems for improved reliability, safety, or drivability. The approach is intentionally balanced – the car looks and feels authentic but drives better than it did from the factory. Typical restomod upgrades include modern radial tyres on period-correct or period-style wheels, disc brakes in place of the original drums, upgraded suspension bushings, a more reliable ignition system, and improved cooling. The original engine is usually retained and rebuilt, often with mild performance enhancements that stay within the spirit of the factory specification. A well-executed restomod is the choice for a buyer who wants authenticity and emotional connection to the original car, but also wants to drive it without the anxiety that comes with pure originality.

A pro-touring build takes the original body of a classic muscle car and completely replaces the mechanical package underneath with modern components. The engine is typically a contemporary GM LS or LT V8, a Ford Coyote, or a built big-block making considerably more power than any factory option. The suspension is a fully modern setup with coilovers, upgraded geometry, and braking to match. The interior is often modernized with contemporary gauges, sound systems, and climate control, while the exterior retains the period-correct proportions and styling with wider wheels and tires that fill the arches properly. The result is a car that looks like a classic muscle car but drives, stops, and corners like a modern sports car. Pro-touring builds are particularly popular with buyers who want to use their car regularly, cover long distances, and experience the visual drama of a 1960s or 1970s American muscle car without the mechanical compromises that come with original drivetrains.

The key distinction is the degree of modification and the philosophy behind it. A restomod upgrades selectively while preserving the original character of the car, including its engine. A pro-touring build starts from the body outward and replaces the mechanical package comprehensively. A restomod owner typically wants something close to original that is simply more reliable and safer to drive. A pro-touring buyer wants the look of the classic era combined with the performance and usability of a contemporary machine. There is no wrong answer between the two – they suit different buyers with different priorities – but it is important to know which you are buying when you evaluate a car, as the two are sometimes marketed interchangeably.

Numbers-matching restored originals have the strongest long-term appreciation track record, particularly at the top of the market where documentation and provenance are verifiable. The rarest variants – Hemi cars, COPO cars, documented Shelbys – have outperformed broader asset classes over the past two decades and show no signs of softening. For the broader collector market, well-documented restomod and pro-touring builds on desirable platforms have also appreciated, though more modestly. The key variable is quality. A poorly executed pro-touring build on a mediocre base car is not an investment. A professionally built pro-touring Mustang fastback or Camaro on a quality base car, with documented build provenance and receipts, holds value well and attracts a consistent buyer pool globally. At Pedal to the Metal, we document every build we produce thoroughly, which protects the value of the car for the buyer long term.

You can, but most serious collectors choose not to. The original drivetrains on these cars were built to 1960s engineering standards, which means drum brakes on many configurations, carburetors that require attention, and rubber components that have aged regardless of how well the car has been stored. More importantly, any mechanical incident – an overheating event, an accident, an engine failure – that results in a component being replaced will compromise the numbers-matching status and reduce the car’s value significantly. Most buyers who prioritise originality and investment value drive their restored cars sparingly and carefully, reserving daily or touring use for a restomod or pro-touring car.

A pro-touring build is the most capable daily driver of the three. Modern suspension, contemporary brakes, a fuel-injected engine that starts reliably in any weather, and air conditioning that actually works make a pro-touring car genuinely comfortable for long distances. A well-built restomod is close behind for drivers who want something more connected to the original car. The numbers-matching original is the least practical for regular use, though many owners do drive them and enjoy them – the experience of driving an authentic, original muscle car is something that no modern replica can fully replicate.

A professionally built pro-touring muscle car starts from €200,000 ($220,000). The final price depends on the base car, the engine package, the level of interior work, and the specification of the chassis and brake upgrades. At Pedal to the Metal, we build pro-touring cars to client specification from our facility in Sneek, Netherlands.

Yes. Our restoration facility handles both restomod and pro-touring projects from the ground up. We can source the right base car for your preferred platform and build to your exact specification, whether that means a subtle restomod that keeps the original engine and character with improved reliability and safety, or a full pro-touring build with a contemporary powertrain and chassis. We keep clients involved throughout the process and document every stage of the build, which protects the provenance and value of the finished car.
