There's been a few Fords have made silly money at auction the last couple of years - RS500 Sierra (I think) also went for the best part of £100k IIRC.
But these aren't cars - these are garage ornaments with silly low mileages on them that can't and will never be used. Absolute travesty IMO, buy a car to drive it and expect depreciation - if it doesn't depreciate by much then happy days.
Personally I wouldn't be buying these kind of cars at that kind of money - if the market wakes up a bit to the overpricing of some models, what are you actually left with - an old Ford, admittedly a nice one but still an old Ford
