SciFrog:

Early FF are under $200k already even with reasonable miles... Actually 3 year old FF sell for same nominal $$ than 4 year old early 612 were at the time, and FF have 25% higher MSRP. FF depreciation is brutal showing that demand is very low even in the used market. Surely the controversial design has a lot to do with it. Personally I like the roof line but not the recessed panels around the rear lights. For most apparently the issue is the roof line.

The problem with the 456 is the interior. It ages badly and has a lot of cheap plastics. The 612 is much much better and has trajectory control...

It will be interesting to see what happens to used V12 FF prices if next year it moves to V8 Turbo only  - though I suspect the V12 will still be available.
