-The 240SX had a couple generations didnt it last until like 1995 or so and became a notchback instead of a hatch?
-The Supra had 4 generations of itself (not counting it being a part of the Celica...which leads me to the Celica)
-The Celica lasted 7 generations (which was more or less replaced by the tC which is on its second generation)
-MR2 i think lasted 2 or 3 generations
-RX8 really only had 1 generation with a facelift, but if you count it as a spiritual successor to the RX7....
-S2000 had 2 generations i guess (i dunno if it actually counts as a generation) which the second one went from a 2.0L engine to a 2.2L engine.
-NSX....well it lasted a long time, and had a facelift which removed the popup lights and replaced it with the fixed lights. I dont think much was changed over the years however.
-Miata has had what 3 or 4 generations now?
-The Genesis coupe kind of sort of replaced the Tiburon which had a couple generations.
-And the 350Z is on its second generation (370z) midcycle facelift.

I dont think this is a 1 and done car.

The S13 240SX was model year '89-'94 and S14 was '95-'98 in the US.

What I really enjoyed was that it got a power bump of over 10% from its first 2 model years in its 3rd year ('91). It's 4th year, they added the convertible. Add to that the S13 was also ~2700 lbs and everyone said it was underpowered (yet I personally loved the way it felt), and you start to realize some of the similarities of these cars.

No.
You'd better get one soon.

In a word... yes. You can bet on it.

Yes. Refresh in 2-4 years. New generation in 6 or 7.

I see the Datsun 200sx isn't getting any love in here. Nissan's S platform dates back a lot further than the S13. I think 5 generations in all for the U.S. market and 6 counting the S15.

i would say give them two years..

Since this was done between Subaru and Toyota I imagine it will have a life much like the S2000.

If the car sells really well then another deal may be in order between the two companies (yes I know Toyota owns a good bit of Hino motors/Subaru). Otherwise, I think we're looking a car specifically designed to test the waters for the market and leave a legacy to improve brand image.

Updated BRZ isn't out of the question but Toyota may end up developing something else with their own chasis and powertrain in that market.

$0.02

350Z & 370Z is technically in Fairlady genre, so they're several generation (6th gen).

i am pretty sure there will be a 2nd gen model. i figure all car makers are looking to go into smaller engined cars. by then, im betting that bmw will have a sub 1 series in the USA, chevy will have that small rwd coupe. betting there will be alot more 1.0-1.5 liter engines being produced also (gas and diesel). heck,next gen FRS could come stock with a 1.5 liter turbo that makes 200hp and 200lb/ft.

My second car was an S12.. Drove over 400 miles to get it. I wouldn't exactly say no love :P
