i see what you mean, but this forun is full of handbuilt hiperformance cars .now thats not always a by word for bomb proof reliability and expert craftmanship. However I feel he would be VERY lucky to swap for an FC. As for my car that like comparing Lennox Lewis to Lisa Simpson. There isnt a car in my price range that i would trade my car for. Especially a four cylinder roadster.
The point I was trying to make initially with the trade wasn't that it is a better car, a more enjoyable car, or for you to keep it. My point was S2k's can be very easy to sell, while the market for swapped Rx8's is fairly limited. Like ncaudio said above, those cars can pull good money, and quickly.
If it financially made sense, ie. the numbers worked, and it was an easy/convenient title swap, it might have not been the awful trade you made it out to be. It could have been an easy way to get your car a new home, and give you something more easily sold. But I will reiterate, that is all dependent on the specific car in question. If it was a piece of shit, then this is all moot.
