50-70mph stats for the E46 or E92 M3

[matth76]

Hi
Does anyone know the 50-70mph time for the for the E46 or E92 M3? Are there any other mid range acceleration times available such as 30-50mph etc?

Does anyone know of any website to see how they compare to other performance cars such as the RS4 and AMG Mercs?

Thanks for any help and info.
