Thinking about a 401/403

[Stefan]

Well sounds like everything I can think of has been addressed. Scrutinise it underneath on a ramp and look carefully at the new paint e.g. around the wheel arches to make sure no corrosion is striking through.
A compression test would be reassuring but it sounds as if mechanically the engine will be tipi top.
If it hasn’t got an overdrive ( essential for the motorway) and anti roll bar those can readily be fitted.
These days we’re looking at restorations of restorations of a 70+ year-old car so much depends on the skill of the ancestral artisans. Most important of all , finally, I would get it well warmed up and drive it very fast to make sure you enjoy it. Some thoroughly restored cars are mere Trailer Queens, this one via SLJ , BCL, and Hackett has the right provenance, and should be a brilliant drive.
