I guess each persons idea of mechanically sound will differ. But I made sure the following were done or at least checked:
Engine oil(5W40)/filter
Fuel Filter
Timing Chain/Tensioner
Cam Belt
plugs/coils
any fault codes?
Diverter Valve
PCV
HPFP cam follower
Oil pickup checked and cleaned
Brakes/Suspension/Tyres - to avoid spending on these shortly after the map.
There may be one or two things Ive forgotten too. But that covers the majority.
