In all, the 545i is a well-balanced rig -- amazingly fast and agile for a car of its size and comfort.
My car has been plagued with electrical issues however, and a glitch with the transmission is enough to force me to replace it.
When driving under slight power between 35 and 40 mph, the car feels as if there is a disruption in the fuel delivery or ignition.
When I first demonstrated this to the dealer, a tech said it was the transmission, it was normal, and by shifting it to sport mode I could eliminate the issue.
Unacceptable, in my opinion.
This isn't "normal" behavior for any car, and I don't want to drive in sport mode to fix a transmission malfunction.
Major buzz kill.
Power and handling; styling (though not for everyone); instrument cluster; nav system.
idrive -- clunky
and sometimes slow to respond; automatic transmission, which disrupts the power delivery between 35 and 40 mph; seats are too hard and slippery; closing the trunk lid requires coordination and heft; exhaust note is akin to a Chevy Malibu; iPod connection is cumbersome (located in the glove box).
