Allow me to draw an analogy.
That's a Milo's Cheeseburger. It's pretty simple, just meat, cheese, pickles, onions and
special sauce on a toasted bun. No lettuce, no tomato, no mayo. Just a few simple ingredients. But it's a really good burger, because each of those ingredients is of reasonably good quality, and they cook it up fresh for you right then. And it has
special sauce.
The FR-S and BRZ are a Milo's cheeseburger. Just reasonably good components put together in a simple format to provide a really good driving experience. The handling and the styling are the special sauce.
Here's a Burger King hamburger:
Let's call that the NISMO Triple Whopper with Cheese, because like the NISMO 370z, it has just about everything on it. But of course you can scale that down. If you take everything off of it and add a little bacon, you get this:
That's the base model 370z that you say we can get for the same price as an FR-S. Okay, it has the mighty horsepower of bacon. But it doesn't have any special sauce. To get something as satisfying as the Milo's FR-S burger, you really need the NISMO Triple Whopper for $45K. But even then you're tasting a mediocre burger underneath that huge splatter of mayo, and you know deep in your heart that you're just covering up a frozen patty that was cooked this morning and has been sitting in a heated drawer for the past couple of hours.
So.
Plain Jane 370z (with bacon horsepower!) for under $30K (with some very aggressive haggling)?
Or fresh, delicious BRZ with special sauce for the same price or less?
I know where I'm headed for lunch.
