The S2k should whip these cars' asses, since it did cost a lot more when it was new. But it was also a good value and well designed car from day 1 (the interior, lights, suspension, transmission etc. are all top notch for the price point and the engine's fantastic). Unless you need 1/4 mile times that compete with a Corvette, it'll always be a great car. I've had two AP1s... My current red 2001 model has 160k miles and still runs like a new car. It's surely not as comfy as a BRZ, but it's a lot more fun.
IMO...
RX8 is cool if you want something very pretty that's quirky and has back seats. Not a fan of an NA rotary which guzzles gas/oil, and I think an S2000 would whip its ass in a drag race. Still has a place in my heart but like the guy said at the end, I don't lust over it.
BRZ/Scion if you want something new (warranty) and easy to push hard safely. I can't imagine picking an RX8 over this car, and the BRZ is especially beautiful. I'd recommend it to a semi-enthusiast / someone new to sports cars that wants supreme bang for the buck. I'd rather drive this in traffic than the other 2.
Also... totally agree about electric power steering. Hydraulic PS is messy, complex, robs power and has no real "connected" feel like manual steering anyway. I've seen Cayman Ss and GT3s with PS failures at the track, making a huge mess and overheating. Properly done electric steering is great, which is why Porsche too abandoned hydraulic. I've had 3 cars with electric steering now... they're nimble when you want it and you definitely get as good of road feel as any hydraulic system if both are designed properly. Hydraulic's going the way of the dinosaur.
