For some, that's also the appeal. There's a lot to be said for not standing out from the crowds always. For me personally, I see the TT as an absolutely fantastic every day car that does everything so very well, but maybe it's not as good as that special weekend car. Well, unless it's the RS of course.
That's pretty much how I view my current MX5, too. It sits just behind the 911 as the best all-rounder that I've ever owned, but it's never going to give you that extra little bit that makes you smile as you start it up every day. Certainly not in stock form at least, but that doesn't mean I don't love it and thoroughly enjoy extracting every last bit of performance from it on a fun drive.
