Restoring one means you get to experience all of this, firsthand, for years to come. In essence, restoring an Audi Sport Quattro is an investment in history, a challenging yet rewarding project, and a gateway to an unforgettable driving experience.

Finding Your Project Quattro: What to Look For

Okay, so you're sold on the idea of an Audi Sport Quattro restoration, awesome! The first hurdle is finding the right project car. This can be the trickiest part, as these cars are rare, and finding a good one can take time and patience. Here's what you need to consider. First and foremost, condition is key. Don't be afraid to walk away from a car that's too far gone. Rust is the enemy. Check the usual suspects: the floors, sills, wheel arches, and chassis. Rust repair can be costly and time-consuming, so the less, the better. Look closely for any signs of previous bodywork, as this could indicate hidden rust issues. Mechanical condition is also crucial. While you'll likely be rebuilding the engine and other components, a car with a well-maintained engine, transmission, and drivetrain is always a bonus. Take the time to inspect the engine, checking for any leaks, unusual noises, or smoke. Ask about the car's history. Has it been sitting for a long time? Has it been modified? A well-documented history can give you valuable insights into the car's past and potential issues. Consider the paperwork. A complete set of documentation, including the original service manual, is a real asset. It can help you identify the car's specifications and assist with sourcing parts. Be realistic about your budget. Restoring a Quattro isn't cheap. Factor in the cost of the car, parts, and labor, and set a budget that you're comfortable with. Don't underestimate the cost of restoration. Finally, take your time. Don't rush into a purchase. Inspect the car thoroughly, ask questions, and be prepared to walk away if something doesn't feel right. Finding the right project car is the foundation of a successful Audi Sport Quattro restoration. With patience and careful planning, you'll find the perfect starting point for your project.

Disassembly and Assessment: The Foundation of Restoration

Alright, you've got your Audi Sport Quattro, congratulations! Now comes the critical first step: disassembly and assessment. This phase is all about understanding the scope of your project and setting the stage for a successful restoration. Start by documenting everything. Take plenty of pictures and videos as you disassemble the car. This will be invaluable when it comes to reassembly. Label and bag all the parts, using a system that makes sense to you. Keep track of what goes where, so you don't have to guess later. Begin by stripping the car down to its bare shell. Remove the interior, engine, transmission, suspension, and any other components that need to be removed for restoration. As you disassemble, inspect each part for damage, wear, and rust. Make detailed notes of everything you find. This will help you create a comprehensive parts list. Assess the body. Look for rust, dents, and any other damage. Consider whether the body needs to be media-blasted or chemically stripped. Inspect the engine and transmission. Check for any major issues, such as seized components or severe wear. Determine whether the engine needs to be rebuilt or if it can be repaired. Assess the electrical system. Check the wiring harness for any damage, corrosion, or modifications. Make sure all the components are in working order. Evaluate the suspension and brakes. Inspect the components for wear, damage, and rust. Determine whether they need to be rebuilt or replaced. Create a detailed parts list. Based on your assessment, create a comprehensive list of all the parts you'll need to replace or repair. This list should include the part number, quantity, and cost. Set up a workspace. Make sure you have a clean, well-lit workspace to work in. It should have enough space to disassemble and store parts. Take your time. Don't rush the disassembly and assessment process. It's the foundation of the restoration, so it's essential to do it right. Disassembly and assessment are critical phases in any Audi Sport Quattro restoration. By taking the time to thoroughly inspect and document the car, you'll be able to create a plan that will lead to a successful restoration.

Bodywork and Paint: Bringing the Quattro Back to Life

Ah, bodywork and paint! This is where the magic happens, where your Quattro starts to look like a Quattro again. It's a critical stage, so let’s dive in. The first step is to address any rust. This might involve cutting out rusted sections and welding in new metal. This requires skill and experience, so if you're not comfortable with it, consider outsourcing this work to a professional. Once the rust is repaired, the body needs to be straightened and smoothed. This involves removing dents and imperfections. Body filler is often used to smooth out minor imperfections. The body should be prepared for paint. This involves sanding the surface to create a smooth, even finish. The body should then be primed. Primer provides a base for the paint to adhere to and helps to protect the metal from rust. The car should be painted. This is where you get to choose the color. The original colors for the Audi Sport Quattro are iconic, but you can choose whatever color you like. After the paint has dried, the car should be wet-sanded and polished. This will remove any imperfections and give the paint a glossy finish. It's also important to consider the details. Pay attention to the details. Ensure that all the trim, emblems, and other details are in good condition. The quality of your bodywork and paint job will have a massive impact on the overall look and value of your Audi Sport Quattro. Don't cut corners! If possible, try to work with a professional body shop. They will have the experience, equipment, and expertise to ensure that your car looks its best. Bodywork and paint are one of the most visible aspects of the Audi Sport Quattro restoration. By taking the time to do it right, you can be confident that your Quattro will look amazing and turn heads wherever it goes.

These forums are a great place to find used parts, exchange information, and connect with other Quattro enthusiasts. eBay is a good place to find used parts. However, be sure to inspect the parts carefully before purchasing them. Consider reproduction parts. These parts are made to the original specifications and are often a more affordable option than genuine parts. If you are struggling to find a part, you may need to get creative. Consider using parts from other Audi models that share the same components. Also, don't be afraid to modify or fabricate parts if needed. The key is to be patient and persistent. Finding parts for an Audi Sport Quattro can be time-consuming, but the reward of finding that rare or elusive component is a significant part of the journey.
