Wow very detailed review Lauren, I had a test drive in one yesterday in the Northwest also, here are my quick thoughts:
The colour was Navy Blue, bit of a boring colour to be honest and doesnt show the lines of the car off very well however the car itself is amazing! Inside is all leather and like you said it's a similar driving position to the 86, I noticed the sills are very wide and the windscreen is pretty narrow (almost like looking through a letterbox) but it gives the car more of a sporty feeling.
I was very surprised how fast the car was and how well it put the power down through the rear wheels. The transmission is savage when flooring it and I've never experienced a car which changes gears so quick! When driving it's pretty quiet inside the cabin however outside it sounds unreal.
However with this being said, when compared to my GT86 I find the A90 boring... yes the Supra is a lot faster but the automatic transmission in it makes the driving experience a bit too lazy because the car does eveything itself. When I was driving home after the test drive, the 86 made me smile more because when getting on it your able to give the car some abuse and I'm physically able change through the gears on the twisty roads myself.
I'm really hoping Toyota are able to give this new Supra a manual transmission option so it gives the driver more of a connection with the car because I feel that's what's lacking the most. I have no doubt there will be a gradual release of different options and specs and it would also be interesting if the car came with a Targa roof like the MK4.
Because of these reasons mentioned above I'm in no rush to put my name on the waiting list with the hope of Toyota listening to people who have similar views to mine...
