The idrive criticisms are generally
overblown. The items you use 90% of the
time are simpler on the 745 than on most
cars (ie big knobs, easy to see and get to).
The other 10% even gets pretty easy after
several months. The bugs are a pain. They
are all electrical except for the sound system
which is so powerful that it causes the
interior to buzz at certain pitches. But the
drive is sweet and is worth the hassle.
The ride, by far. I also like the auto-park
feature that puts the parking brake on when
you stop at a light and disengages it when
you step on the gas.
The SMG on the 2002 M3 would have been
a nice feature as well as steering wheel
buttons that shift up as well as down (The
745 only downshifts). The navigation
system should use a DVD instead of a CD
(this one baffles me!).
