Same as what everybody else is saying.
Without a manual I wouldn't have *any* interest in it. None.
BMW is a competitor, but sadly I've hit my lifetime quota of BMWs. I owned ONE--that's enough. I loved the way it drove, the ergonomics, the controls, everything dynamic about it (except perhaps the rubbery shifter). The endless check engine lights and failures were demoralizing. The M3 is scary ugly but I might even be able to get over that if BMW didn't build disposable cars.
"6-spd and V8, end of story."
Hard to argue with that! As such, I also thought about a Mustang, perhaps the Mach 1. Just like the BW5 better. Would have preferred a 2-door, but you can't have everything.
Honestly, I feel like Honda is missing the boat here. The Acura Legend was a great car back in the day. Not the performer that the BW4 or BW5 are, but I wonder what a modern Legend could be. 2-door, 6-cylinder, good mix of performance and comfort. A modern version of the Legend would be the archetype of what I'm looking for at this point in my life.
As for what else I "did consider," that's not the correct verb tense. I am "considering" (present tense) a few other cars. Not direct competitors, but complementary cars.
I'll buy a BRZ before this model cycle is done, when it's more available, it is a FANTASTIC car. I loved the old version, even with the underwhelming engine. The Bronco, which I just bought, is a surprisingly simple and satisfying drive. Maybe a Civic Si/Acura Integra for a fun & practical daily driver.
Just a nice selection of manual transmission vehicles in the next 5-10 years while I can still get them. Also thinking about family (daughters, nephew, niece) who may need used cars at a family discount and some encouragement to drive a manual.

Then I'll go electric when that market is much more mature.
