A 997 without issues would be more in the 30.000-40.000€ range, depending on cosmetics. The cars were 100.000€ when new (without extras), don’t forget that. And it doesn’t have the “fried egg” headlights - that alone commands a 5-10.000€ premium over a similar 996 to many people.
Completely unjustified to me, but hey,…
