First, some good news – the Testarossa’s bodyshell is aluminium, with steel doors and roof, so corrosion is low on the worry list, although old paint is prone to flaking off.
And now for some bad news – the cambelts must be replaced every 15,000 miles, and it’s a daunting, engine-out job. Other than that, the flat-12 engine is pretty robust.
People don’t regard the Testarossa as a daily driver, so they often stand unused in garages for long periods – which is bad for tyres, seals, gaskets and hoses. A specimen that’s racked up the miles with good maintenance is probably best.
