i personally dont think you can include the RS260 C24 in a comparison to M35s. its basically a gtr wagon, no such model exists in the M35 range.
so that model aside, compare each model with their respective counterpart. take looks out of the picture because we will NEVER agree.
compare the rest, youll have to agree that the M35 wins on most comparisons. there is a reason for that. there is 6-10 years of technology change in M35s.
so whoever asked the question originally, go drive them all, and tell us what YOU decided.
