95 Alfa 164 ls, 07 Quattroporte exec. 07 Santa Fe.
The clutch wears out after 1,000 miles and costs $15,000 to replace, the story goes.Your analysis is sober, and your opinion well-informed. Unfortunately, the "value" of these cars has been affected by people who are not so well-informed. According to the comment section of every BaT Quattroporte auction, the Duoselect is a piece of trash that no one should ever buy. The clutch wears out after 1,000 miles and costs $15,000 to replace, the story goes.
I think that is part of the resale problem. If these were, say, a $3000 repair (which is perfectly reasonable considering there is no "magic" material in there, I expect the Duo-select reputation would be acceptable. But when a repair can cost as much as the entire car...
The resale values for these cars, ZF included, suffer because of the high cost of parts and repair bills, not necessarily due to reliability issues. IMO.
