Hi Pat,
They're generally quite solid, but there are a few crucial checks to make. Alternator belts can wear and make a horrible screeching noise when they do. The HDi engines need an additive put in at 60-80,000-mile intervals. A heavy clutch pedal may mean clutch failure is imminent. There are diesel particulate filter issues - if the DPF light comes on and stays on, run the car at medium revs in a low gear for several kilometres to try and heat up the exhaust enough to burn out soot from the DPF. If that doesn't work, it's an expensive part to have replaced. Dual-mass flywheels can get warped and cause a juddering effect. A lumpy idle or excessive exhaust smoke may mean that the exhaust gas recirculation valve needs replacing.
Inside, the radio and its LED screen can be fragile while, if the air conditioning isn't puffing hard enough, it usually means that the pollen filter needs emptying. Underneath, watch for the front suspension being out of alignment and for excessive tyre wear - 407s were always quite hard on their tyres. A groaning power steering system means the pump needs replacing too.
