Incredibly expensive to maintain the V8 Bi-Turbo
 Constantly requiring expensive maintenance. Bought with 60K miles in 2015. Have spend $10,000 -- and this it at least 1/3 less than what the dealer would charge. EVERYTHING requires massive labor and parts are amazingly expensive. My 6th BMW, but my first V8 Bi-Turbo.
