What are the Common Challenges Faced in Classic Car Restoration?


Restoring a classic car is a thrilling blend of passion and precision, and it is both a hobby and an investment. In the best cases, it transforms into a beautiful showpiece or the dream car you can drive every day.

However, not all restoration stories are smooth sailing. It’s essential to be aware of the significant challenges that come with car restoration. We’ll look at some of the most challenging parts of this exciting journey.

1. Sourcing authentic parts

One of the most significant challenges in classic car restoration is finding the right parts. Authentic parts are essential for a true restoration, but they are often rare or nonexistent. If you desire to keep the authenticity of the classic car, then be prepared to go on a hunt.

Finding authentic parts for an old car can be quite a task. You can’t just pop into a regular auto supply store for these rare items. Since these parts are no longer manufactured, looking for parts involves exploring various online sources, connecting with car collectors, attending swap meets and auctions, and even rummaging through junkyards.

Locating items like vintage car stereos, steering wheels, or even specific upholstery materials can be particularly challenging. Sometimes, restorers need to contact the original manufacturers for custom-made replacements, which can increase the project’s cost significantly.

One of the toughest parts to find is a functional engine. When you find one, a lot of work is involved in ensuring it operates smoothly.

It can be a time-consuming and sometimes frustrating process, but with patience, you can often find the perfect fit for your classic car.

2. Matching the perfect body paint color

Choosing the right body paint color is a well-known challenge in car restoration. If you watch restoration reality TV shows, you’re probably already aware of this. Many of the paint colors used on cars 50 to 60 years ago are no longer produced, and detailed information about these original shades is very little.

Often, restoration experts engage in a trial-and-error process to replicate the exact original color. This involves examining remnants of the old paint and searching for historical photos of the car in its original hue. The process includes careful color mixing and ensuring the color remains true under various lighting conditions.

This task requires a lot of effort and precision, so it’s essential to select a car restoration shop with extensive experience and the latest technology dedicated to this part of the restoration.

3. Looking for someone with the skill and expertise for restoration

Restoring a classic car is a complex task that requires a wide range of skills. One must be part mechanic, part historian, and part artist. Understanding the unique mechanics of older vehicles, many of which lack the electronic components of modern cars, is a skill in itself. Moreover, different eras and models have their unique quirks, requiring specialized knowledge. For many, this means years of learning through trial and error or the expense of hiring skilled professionals.

When it comes to hiring professionals, it’s important to look for those experienced in restoring classic cars or are at least very interested in one if yours is going to be their first classic car project. Otherwise, some pros may convince you to replace parts or go for paint colors that are not the same as the original just to make the process go faster.

4. Balancing originality and modernization

A critical debate in the restoration community is between maintaining absolute authenticity versus incorporating modern technology for reliability and safety. Purists argue that altering any aspect of the car’s original design diminishes its historical value. Others advocate for subtle upgrades like disc brakes or modern suspension for better drivability.

Striking the right balance is often a personal choice but can significantly impact the restoration process and the car’s final value. If you decided at first to be committed to preserving its originality, you might get challenged to stick to your decision along the way should issues regarding original parts arise.

If you’re open to partial restoration with some modern upgrades for better performance, you’ll need to decide which improvements to make. Since a car is a complex assembly of parts, changing one can affect how another functions. It’s wise to discuss with your restorers how certain upgrades might impact the original components you want to keep.

5. Finding the time

Restoring a classic car is a time-consuming endeavor, often taking longer than anticipated. The time it takes can vary widely, from several months to years, depending on the extent of work needed and the resources at your disposal. If patience or free time is in short supply for you, it’s important to consider whether this project is the right fit.

The time required can depend on various factors, such as the car’s model, its condition, and the level of restoration you want. Setting a definite completion date for a classic car restoration project is tricky because there are often unexpected issues or delays that arise as you move from one task to the next.

Juggling this with a busy schedule can be quite tough, leading many aspiring restorers to give up. Being aware of these challenges can better prepare you for the journey of car restoration, increasing your chances of success.

6. Maintaining your budget

Staying within your budget is another common hurdle in classic car restoration, especially for those new to auto restoration or mechanical work. Labor costs can quickly escalate. It’s crucial to carefully plan your spending for each phase of the restoration to prevent your expenses from skyrocketing.

The cost of parts, tools, and professional services can quickly add up. Moreover, the value of the finished car may not always reflect the investment made, making this a labor of love rather than a financial investment.

7. Handling the details

Restoring a car is largely about dismantling it, fixing or replacing smaller components, and then putting it all back together. This includes working on the engine, transmission, brakes, interior, lighting, and more. The key challenge is to meticulously disassemble everything, organize the parts, and document the process with photos. Many restoration projects have been abandoned because people lost track of where each piece belonged and felt overwhelmed.

8. Achieving full functionality

Getting a classic car to run as it once did isn’t straightforward. Using a newer engine is often necessary, which can impact how other parts operate. If you do manage to get an old engine running, it’s important to understand its limitations. Remember, older models were updated for a reason. The same issues they had when first released will likely still exist after restoration.

9. Dealing with rust and corrosion

Dealing with rust and rot is a common part of restoring older cars. If you’re lucky, you might find a car that has been sheltered most of its life, but rust is usually an inevitable challenge, as many vintage cars have been exposed to the elements for years.

Extreme rust can transform a fun project into a daunting task, and some experts might even refuse to work on cars with severe rust damage. Additionally, vintage cars with wooden frames face the risk of rot, which can sometimes make restoration unfeasible.

Dealing with rust is not just a cosmetic issue; it often involves extensive work, including cutting out and replacing entire sections of the chassis or body. This process requires not just skill but also an understanding of the car’s structural integrity.

10. Handling a convertible top

Driving a convertible is an unmatched experience, with the sun shining down and the breeze flowing. The catch? Many old convertibles have fabric tops, which deteriorate over time. Ideally, you’d replace the top with one that matches the original manufacturer’s design. But sometimes, there’s no direct replacement available for the car you’re working on.

Your choices are limited: get a custom-made top, which can be quite costly; skip restoring the top, limiting your driving options and affecting the car’s value; or consider dropping the restoration project altogether.

11. Prioritizing safety

Vehicle restoration comes with its set of risks, making safety paramount in classic car restoration. It’s essential to guard yourself against hazards like fumes, sharp objects, and heavy debris. Always use the right safety gear, including goggles, gloves, and protective clothing, to minimize exposure to dangerous materials. Various automotive gloves are available, so choosing the right type is crucial for ensuring your safety.

12. Navigating legal and regulatory issues

Registering and insuring a classic car can be a bureaucratic challenge. Emission standards, safety regulations, and insurance policies vary widely and can be particularly stringent for older vehicles. Navigating these regulations requires research and sometimes creative solutions to comply with modern standards while maintaining the car’s classic integrity.


Restoring a classic car is no small feat. It demands time, money, and technical savvy. Whether you’re restoring the car for personal enjoyment or aiming to showcase it at car shows, your dedication to the project plays a crucial role in its completion. With ample funding, a positive attitude, and the resolve to tackle the challenges mentioned earlier, you’ll see the fruits of your labor sooner, making the success even more gratifying.
