Have you tried a McLaren 650S? Admittedly I've not driven many cars in this segment, but of the ones I have, nothing comes close to giving you super levels of ride comfort when you need it, and then huge amounts of grip and stability when you don't. Also, the braking ability is immense.
Year old 650's are now into your FF price range and in relative terms appear to hold their price with the competition. Alternatively, snapping up one of next years 675LT spiders, while you still can, would let you run it for a year with minimal loss as limited numbers mean used 675's are in demand.
