Price is high for the Dutch market, but if this bike is exactly what you're looking for then €400 may not be too bad. The new Brooks bits are fairly expensive, and it sounds as if the bike is ready to ride.
The fork is not original to the bike, which would bother me at that price level.
WRT to size: 60cm should be fine. I have a 35" inseam and ride 62-64 cm.
