Sounds like lexus went hardcore on the 16, then tuned it down a bit for the 17+

Theoretically, the 17 and up should perform better because of the adaptive suspension. This however depends on driver since some like fixed and some like adaptive. Also, the 2020 MY has additional suspension tweaks. I don't think Lexus tuned it down after 16.

Not so sure about this but my 17 does not have the all speed cruise control, it cuts off at 30-40mph. That's one feature that I'd like to have that I forgot to mention in my previous post, the 18 has all speed cruise control. If we're talking about performance difference, the 17 and 18 are "upgrades" over the 16 with no changes between 17 and 18. The rest are minor technological features.

"I do have to argue that the variable suspension is on paper, better than the standard suspension. I also believe that this also adds "value" to the 17 and 18s. Review sites such as Motor Trend etc., bashed the GSF for opting for a traditional suspension system that other cars such as the Cadillac CTS-V have. I have driven my GSF on the track and it handles beautifully. However, I have not driven a 16 so I can't compare suspensions.

Lastly, in 10 years or so, if this car is somehow desired, I do think that the variable suspension system will be something that future used car buyers consider when shopping for GSF. So something to keep in mind if you plan on keeping it long term.

Edit: For the lane assist, my 17 has the lane alert system where it alerts but doesn't correct steering. I believe that the 18 has lane assist system where as it will correct steering. So I believe you are right."

I have a 2016 and still with less than 35K miles, sometimes I wish it had an adaptive suspension but when I corner while accelerating you will realize how fun and steady the suspension is, you feel the real traction and power at high speeds.
Also it has the active lane departure system and it auto corrects the steering wheel.
Anyways keeping the cars in original condition would be the best option as there's o production of GS-F's.
I have PPE equal length headers, APEXI non-resonated mid pipe and the electronic tuneup from RR Racing -I think it pulls closer to 540 crankhp (yes it goes above the top speed of 168MPH (but still have to see if I could hit 190MPH-thank you TX freeways )
I know this because a Dodge charger SRT could not keep up with me with its 485crankhp motor-I bet he blew up the head gasket as there was smoke coming from his hood.
