I drove my dad's 2006 MX-5 yesterday and it's fun. It's even automatic (@160hp) and has enough power. I love the seating position and the sound. It's no wonder it's such a popular car.
I don't know how it will compare to the FRS other than they are sporty cars. Obviously the FRS is a 2+2, so there's a little more practicality, but I think they'll be pretty much the same; with the FRS being a bit quicker. The MX-5 is really plasticy on the inside, so I think the newer FRS will be a bit more nicer and comfortable.
And about the debate about why only 200hp out of the FRS engine, and I'll bet that the engine was made to be tuned. But that's just speculation on my part.
