Each required visit to the dealer for repair results in having to return to have at least 2 additional items corrected. Idiot drive aside, safety issues are of primary concern. 4 months for BMW to figure out they had to replace the modual that controls the remote key (Plastic emergency key required to open a $85,000 car). Intermitant operation of headlights and tail lights. Engine goes into idle mode at the slightest touch of break pedal. I thought the 2000 S-430 was trouble prone but would gladly trade back. The 745LI is my wifes car which I have limited her use to daylight driving only. For security reasons, she drives our Expedition or Town car when venturing out after dark.
Acceleration, panic stops and rear leg room.
GO BACK TO THE BASICS. Bells and whistles are no substitute for reliability.
