I test drove the S5 when I leased the M3 back in late 2008. No RS version available but I had also driven the RS4.
The S5 was not even worth the time and is not a fair comparison; way too soft. I really like the RS4 but it felt heavy compared to the M3 (sedan v sedan); perhaps the AWD... Will have to check out the RS5. Have my heart set on a 911 S (spring/summer purchase hopefully) but will check out all my options before I make a final decision.
Thank god i got rid of the Z4...
