What the heck are you all sad about? Almost no one should be buying one new and you have at least 5-9 years of being able to buy finely depreciated used examples!
There are definitely things to be sad about. Future Mustachians 10 years from now will have less selection for practical efficient vehicles. It indicates a fall in demand for efficient vehicles. Honda went through the trouble to design a brand new Fit and decided we weren't worthy of it. Its discontinuation means one less vehicle I can recommend to less Mustachian people that insist on a new vehicle.
Isn't Toyota going to make basically everything hybrid in the short to medium term?
Many of (all?) their sedans are available hybrid (MPGs from mid 40s to early 50s). As is the Rav4 (~ 40 MPG). All of these vehicles have higher MPG than the FIT (high 30s).
The new Venza (40 MPG) and Sienna (33 MPG) will be hybrid only.
On that list, the only vehicle with lower MPG than the fit is the Sienna and it's pretty clear that they aren't exactly competitors.
The way I see it the main advantages of the Fit were low cost, fuel economy, and flexibility via the hatchback. But something like the Corolla Hybrid would be significantly better in terms of fuel economy and still at a fairly low cost. I wish they would make a Corolla Hatchback Hybrid, but I think they're worried about cannibalizing the Prius market.
Anyway, I think we will have way more selection for fuel efficient vehicles with high reliability in 10 years. I've got a 2011 Venza that I'm hoping lasts till 2025 or so. I think we'll have lots of great options by then.
I'd bet in a decade the standard will be more like plug in hybrid than just the current hybrids that generally have a higher MPG than the fit.
