It's your lucky day, I'm 202cm/6'8".

I've never sat in an 850 so can't say anything about that, but my 740 needed the sunroof removed so that I could actually sit up straight. Also, depending on your proportions you may need to make modifications to the seat rails - mine had split pins in that stopped it moving all the way back, once I knocked those out it was much more comfortable.

A final thing to note is that the headrest on the seats is non-adjustable. It's just about OK for me but if I fully sit up straight, the bottom of it digs into my neck and shoulders a little. Ideally I want to change the driver's seat to something more comfortable, but I have to find the right seat.

If the 940 100% doesn't have a sunroof (some have a solid panel that retracts and isn't particularly visible in photos), I'd say it's worth sitting in for sure.
