Hi, I am brand new in the BMW M5 world. I just acquired a mint M5 from 1999. It has only 45,000kms and was parked most of the time in a garage (the previous owner was a pilot for Gulf Air airline).
I checked the whole car through the local dealer and even did a main maintenance to be sure everything was ok on the car. They confirmed that the car was fine. However, I have one concern:
The acceleration is not frank and have little "holes" during smooth acceleration. Also, if I accelerate full throttle, I feel that the car does not give all the power it has. For instance, sometime, just by releasing the accelerator a little bit, more power is being delivered for a couple of second.
All filters have been changed, as well as all the spark plugs.
Does anyone have felt the same thing on their M5? I would really appreciate your help!
Thanks in advance to all of you!
