My only regret is that I would have preferred a Porsche Caymen, but at literally 1/2 the cost for arguably 90% of the performance - my FR-S fits the bill nicely.
The only real regret is having to originally explain to everyone that asks "Nice car, what kind is it?" to which I say "It's a Scion" and they look at me with a blank face for a second, and then say "Is it fast?" and I say "No, but it handles like a dream" yada yada yada...
I've since learned to answer "Nice car, what kind is it?" with "It's a GT-86" and "Is it fast?" with "It is now".
