Hi, Jerry,
All versions I've driven (standard production) except the 850CSi were a bit ... sluggish, though they did pull seemingly forever.
The 850CSi was the exception, and of course, the Dinan twin turbo was a monster.
I find this so hard to write, because the body has really stood the test of time (one of those "I don't like it" coming off the E24 6 "The Shark" series...and you know how much I loved the E24 M6...) but I always get frustrated with bodies that promise things the drive train can't deliver...
But when other, lesser cars start to flag, the 840 and 850 just keeps on keeping on...
I just wish people knew what they were getting into with the 8, and the body, as sexy as it is, only fuels the mismatched expectations.
We've got to do a car event, Jerry.
