S2K isn't a "better" car than the 86... just because it's faster. Plus, OP stated clearly that he'd rather have something more conservative because it will be passed down later on. I'm not putting down the Honda because I've owned one, and yes the F20C and the later F22C1 are absolutely a couple of the best inline four engines ever produced by anyone. Couple that with unbeatable Honda reliability and you have a terrific car, but I will say that the BRZ/GT86 handles much better because it has a lower center of gravity and less body roll.
In layman's terms, the S2000 is faster in a straight line but the Subaru is a more comfortable ride and is cheaper to insure too. How do I know, because I've owned both. The only reason I sold my S2000 was because someone made an exceptional offer and considering it was seasonal, the time was right. I did lose sleep the following few nights tho, she was a black AP1 and I loved her.
"
Engine is special, trans is up there amongst the best I have driven, top goes down, faster than the brz ."
being faster is only one factor.... and considering the S2000 came out in 2000, does that speak highly of the honda or poorly of the BRZ? I know hp and straightline speed don't tell the whole story, but #1 thing complained about with the BRZ in every single review I have ever read/watched.... under powered. owners are begging for more power. I am not saying it has to be hp dominant, but I think an extra 20-30 whp, would change that car a lot. that said, an extra 100, might wreck it, making it unbalanced.
You think putting the two cars side by side, driving them back to back, you come back saying the BRZ is the one you prefer to drive?
I always though the S2k was a bit of a laugh, not much of substance. ... but that's only till you drive one.
the s2000 can be had for that 18k dollar budget. Keep it in nice shape, and not only will it reward you as a driver/owner, it will still be worth that 18k dollars (likely more) yrs down the road, if you chose to sell it.
think you will lose sleep if/when you sell your BRZ/FRS?
again, not saying the BRZ is a bad car at all. I am just sat at 17-18k dollars, it isn't even on my radar. further, the S2k is just one car I would buy before the brz. Many others are on that list as well.
