Sure, happy to help, let me know if you have any other questions.
Honestly, it sounds like an automatic would be fine for this particular car. I mean having an auto E30 isn't fun per se but the 850i is a pretty soft car, I didn't really miss the third pedal, all my cars are manual expect 2008. It would definitely start to move when it kicked down.
Not that you asked me but I suggest getting the most well maintained auto and spring for a nice aftermarket exhaust and still have a $10-20k left over, lol. Comfortable cruiser that would snarl when revved.
The manual seems to double the price of an automatic in this particular model.
I say exhaust because the collector guy had a Testarossa with stock exhaust, pulled hard but boring!! The maranello has a Tubi and sounds unbelievable, both V12s, really changes the character of the car.
