I agree with what you are saying, and it is helpful to hear it from somebody else other than the voice in the back of my head. I bought a gorgeous Audi R8 2 years ago and planned to keep it forever because I love the sound of a V10. Once I sat in it and drove it for a little bit, I found that my head brushed against the ceiling just a little bit. No matter how much I set the seat I couldn't get it so that I was in a reasonable position and not touching the ceiling. I was so mad, but there's nothing near me to test drive. After that, I did start flying places to test drive cars to see if I fit in them and was comfortable. I think I will try to see about test driving the Lexus, but I'm also a bit frustrated with Cadillac for not having a new configurator and press pictures of the new blackwing in all of the updated colors.
When I did have the 5VBW, I loved the transmission, the sound was pretty good, the torque was awesome, and it was comfortable. I didn't love the touch screen setup that seemed a little dated even when new, and the stereo was a little on the disappointing side. The new model obviously has the refreshed touch screen setup, and other than the slight changes to the exterior, it's mostly the same car. I think I would be pretty happy with it, but I think I will at least go test drive a couple cars before I place my order.
