That’s still only 4,000m per year...Can the ppl do a compression test?
Clearly worth considering. It’s cheaper to get spanner work done than bodywork so if it’s solid, watertight and all there, and currently runs, why not? Maintenance is key though... You’ll not find out how they drove it but these engines are not fragile high performance Italian engines (nor generally not thrashed beyond tolerances). I’d be thinking about an engine rebuild budget but if it’s running ok, and doesn’t leak etc, you don’t need to rebuild immediately. If it’s a bit “lumpy”, there’s all manner of help on here to address running issues.
Mine has nearly 150k on it but the engine has been rebuilt twice along the way. It’s like Trigger’s Broom/Theseus’ Ship
