I think the Is 350 has alot more class when you pull up in it verses the looks of the BMW 135. Also, the 135 is a first year model, and BMW has allways had electrical issues, and bearing problems. The 135 is new, so I can't say these are issues with that model, but it is pretty general. I also think about 2-5 years from now, the IS 350 has alot more staying appeal. I just don't like the new design of the BMW's as much as the previous model design. I like the M3, M5, and M6 and the SC, but all the series cars look out of place. Like the 3 series, and 6 series don't look anywhere near as nice as the M series flagship for each class.
