Personally brought from Switzerland
The owner of this Ford Mustang Mach 1 personally brought the car to us from Switzerland. It was an original 1970 Mach 1 with a manual transmission and a 390-cubic-inch V8 engine, listed as original (approximately 6.4 liters). This wasn't some anonymous American car project, but a personal classic that was to be returned to Switzerland after restoration.
Right at the beginning, however, an avoidable mistake occurred. The car wasn't properly prepared or registered with Swiss customs before delivery. This resulted in unnecessary tax burdens for the project. This is an important point, especially for Swiss owners: before a vehicle is brought to the EU for restoration, customs and tax issues must be clarified beforehand. Doing so afterward is usually more complicated, expensive, and frustrating.
Previous repairs involved a lot of filler.
The Mustang had been repaired and painted before, but not professionally. After removing the old paint layers, it became clear that previous body damage had not been properly repaired. Instead of proper sheet metal work, there was an excessive amount of filler in the area of the C-pillar and the rear fender on the passenger side.
In some places, there was up to three centimeters of material. That's no longer a normal repair, but a substitute for proper bodywork. Such layers conceal damage, alter edges and surfaces, and will crack again sooner or later. Poor workmanship is particularly noticeable on a Mustang Fastback or Mach 1 because the rear quarter panels, roofline, and C-pillars contribute significantly to the car's overall appearance.
Typical Mustang rust spots
During the restoration, the typical bodywork points of a classic Mustang were inspected and addressed. Three areas are particularly important: the cowl/water box area, the torque boxes, and the rear quarter panels with wheel arches. The water box is notorious on the Mustang because moisture can remain undetected there for a long time. The torque boxes are structurally crucial, especially in V8 vehicles. And the rear quarter panels often reveal whether a car has been properly repaired or merely cosmetically smoothed over.
Therefore, a beautiful paint job wasn't the only priority with this Mach 1. First, old defects had to be rectified, sheet metal damage properly repaired, and the bodywork restored to its original, honest condition. Only then did a new paint job make sense.
Customer-requested color and modern Mustang tone
At the owner's request, the paint was not restored to its original shade, but changed to a current Mustang color. This was a conscious decision by the customer and suited the character of the project. The car was not intended to have a strictly museum-like appearance, but rather to be a classic Mach 1 with a personal touch.
Such decisions are legitimate as long as they are clearly stated. A restoration doesn't always have to be a complete return to factory condition. What's crucial is that the technical components, bodywork, and workmanship are sound and that the modifications don't obscure what was actually done.
Cooling, stainless steel exhaust and seating position
The 390-cubic-inch V8 had thermal issues. These were solved with a high-performance radiator and a manually activated fan. Large V8 engines in classic American cars are particularly sensitive when the radiator, airflow, fan performance, and idling conditions are not properly matched. A beautiful engine bay is of little use if the car overheats every time it's driven slowly.
In addition, the Mustang received a custom stainless steel exhaust system. The interior was partially refurbished. One small but crucial detail for the owner was the seating position. By repositioning the seat rails, the driver's seat adjustment was improved. Such modifications may seem insignificant, but they significantly alter the driving experience. A car can be incredibly powerful, but if the driver isn't properly positioned, it's no good.
Ready to drive back to Switzerland
The chassis and brakes were overhauled, the car was locked up and returned to Switzerland ready to drive. The result was a successful Mustang Mach 1 with a powerful V8, improved cooling system, clean bodywork, stainless steel exhaust, and a seating position tailored to the owner.
The owner later rewarded the project with a 5-star Google review. We're naturally pleased about that, but it's not the most important part of this story. The more important lesson is this: With a Swiss classic car, customs and tax issues must be clarified before delivery. And with a restored American car, no one should trust the paintwork before the bodywork has been inspected.
This Mustang Mach 1 clearly demonstrates both points. A powerful car can bring a lot of joy. But only if three centimeters of filler under the paintwork don't replace the actual work.
