Ok let's not mislead you
I am comparing the highspeed ride say... Hypothetically 160kph... Of a fully loaded 135 coupe (sans M package) vs e39 540 lowered with 265-19s. The 135 doesn't feel as planted in the lane. Bear in mind though, this isn't stopping me from ordering a 135 cab next week!
For my wife, her old car was a Ford Focus ZX3. This car is now a dream to her with comfort access and all, lol.
