Rust is a major concern, especially in areas with harsh winters or coastal climates. Check the body panels, frame, and undercarriage for any signs of corrosion. Repairing rust can be costly, but addressing it early can prevent further damage. The original engines, while reliable, may be showing their age. Common issues include worn piston rings, leaky valve seals, and carburetor problems. A compression test can help assess the engine's overall health. Consider a rebuild or replacement if necessary. The 3-speed automatic transmission is generally robust, but it can develop problems over time. Slipping gears, rough shifting, and fluid leaks are signs of potential issues. Regular fluid changes and maintenance can help prolong its life. The electrical system can also be a headache. Old wiring can become brittle and corroded, leading to shorts and malfunctions. Inspect the wiring harness, fuses, and connections for any signs of damage. Upgrading to a modern electrical system can improve reliability and safety. The brakes and suspension systems may also require attention. Worn brake pads, leaky brake lines, and sagging springs are common problems. Replacing these components can improve handling and stopping power. Interior components, such as upholstery, appliances, and plumbing, may also need to be refurbished or replaced. Sourcing original parts can be challenging, but there are many aftermarket options available. Despite these potential problems, the 1978 GMC Vandura 3500 is a rewarding vehicle to own.
