Wow, what a beautiful car. I still love the M5 for its perfectness in all categories. The S-T-R matches the M5 in engine and interior capabilities, but it cannot beat the M5's refinement, gearbox, and chassis. That said, I chose the M5. The S8 is way too soft for me and the E55 has never done much for me. What do you guys think? Feel free to post away
