Well said, M5Mark.
I too was also considering a Lexus prior to taking delivery of my M5 last year. I even went as far as going on a test drive of the LS430 and the GS430. The LS430 was just too smooth for my tastes. I felt like I was being "distanced" from the road. It's not a driver's car, it's a cruiser's car I thought to myself. Not what I was after. The GS430 was one step closer to being a driver's car but still not what I wanted. And so, I waited.
By the time I picked up my M5, both Lexus cars were but a distant memory.
