The interior is one of the most important parts of any classic Commodore restoration. Whether you own a VB, VC, VH or VK Commodore, the condition of the cabin plays a major role in both driving enjoyment and vehicle value.

While many early Commodores remain mechanically sound, their interiors have often suffered from decades of sunlight, daily use, moisture and neglect. Cracked dashboards, sagging roof linings, worn seats and faded trim are common issues across virtually all early models.

Fortunately, most interior problems can be repaired or restored. From simple cleaning and detailing to complete retrimming projects, there are solutions available for almost every budget.

Is Interior Restoration Worth It?

Absolutely.

Interior restoration often provides one of the highest returns on investment in any classic Commodore project. A tidy, comfortable interior makes the vehicle more enjoyable to drive and significantly improves overall presentation.

Many buyers place as much value on interior condition as mechanical condition.

The interiors of VB, VC, VH and VK Commodores have endured decades of Australian heat, sunlight and daily use. As a result, even well-maintained vehicles often require some level of restoration.

Fortunately, most common problems—including sagging roof linings, worn seats, faded trim and damaged carpets—can be repaired or replaced. Whether you’re completing a concours restoration or simply refreshing a weekend cruiser, improving the interior can dramatically enhance the ownership experience.

A clean, comfortable and well-presented cabin not only preserves the character of these iconic Holdens but also helps ensure they remain enjoyable classics for years to come.
