Buying Tips for the 1978 Triumph Stag
- Demand a stone-cold start and allow the engine to idle for at least fifteen minutes, monitoring the temperature gauge and feeling across the radiator face to confirm absence of cold spots or silted lower cores.
- Inspect the structural A-pillars, inner sills, floorpans and the T-bar roll hoop joints for tinworm; structural body repairs on a Stag easily exceed the cost of an engine rebuild.
- Check documented history for duplex timing chain renewal intervals (required every 30,000 miles) and the presence of upgraded cooling modifications such as high-flow radiators and auxiliary electric fans.
- Confirm whether the original Triumph 3.0 V8 is fitted or if a conversion (Rover V8 or Ford Essex V6) was performed; factory-original V8 cars command a substantial market premium among UK collectors.
