I acquired mine sight unseen, without ever driving one or even sitting in one. Got it brand new.
I had about four months of lead time to look into things and ponder the car and learn about it, and I kept hearing horror stories from people who thought the seat didn't go back far enough. I started to get concerned.
Then, in March, I got the car. Got in it, and within three minutes realized it was VERY comfortable. It was "just right". Perfect.
I have 10K on the clock now, and most recently came back this week from a 1000 mile trip. The car is VERY comfortable. It doesn't push itself onto you; in many respects, it's like a waterbed. I don't even feel the seat, don't feel any need to squirm or reposition myself for any reason. I get out after 6 hours and am perfectly comfortable.
I'm 6 foot 1, 250 pounds.
If you were comfortable during the test drive, chances are you'll be just as comfortable long term.
