I would argue the FR-S is a halo car not a niche car. It's about as garden-variety a sports car as you can get. Problem is, for what they cost it's competing with the Hyundai Genesis, which has a lot more utility (and better build quality).

I'd argue that halo cars are often niche cars. Keeping in the theme of Japanese automobiles, we can look to the Acura NSX and Lexus LFA as examples. Part of the problem with the FR-S here in the states is that competition is fierce. I would know. I cross shopped it against a Ford Mustang GT, Mazda Miata, and Subaru WRX. There's tons of other cars in or near the segment, such as the Dodge Charger and Challengers, Chevrolet Camaro, Hyundai Genesis, Civic Si, and probably some others that don't come to mind right now. Competition is fierce right now, which is great. I'm not denying though that if you get an FR-S or a BRZ, you're probably gonna make some concessions.

I'm guessing you're not in Los Angeles. Teslas have a few advantages going for them . . .

I will admit that I do not live in Los Angeles nor do I have the income to even entertain the idea of purchasing a Tesla, so I'll concede to your better judgement on that. I do have to say, you bring up some pretty compelling advantages.

The 370Z is crazy fucking expensive for what you get.

If I remember correctly, which I may be wrong, the 350z started out reasonably priced. When it became the 370z and as time went on, the prices really started to jump up. It's not a car I would want and for that kind of money I'd indeed get something else myself, which is probably the logic behind its declining sales. At this point though, Nissan has pretty much wrung out the VQ37 engine for all its worth. I don't think the engine nor the 370z is long for this world.
