I like sitting upright which is not what the Leon is all about. (l
Think that's exactly what I've experienced with the MK1 and MK3 Leon. Unfortunately I had to scrap a focus c-max recently and that had a very comfortable high driving position that I think may have spoiled comfort for me in other cars.
I had a cheap mk1 Leon as a temporary car until I got my new car through work (Leon MK3 SE model) and had to accept a more reclined driving position than C-max with it being a smaller car but I did get used to it.
Then when I did get my MK3 I tried to emulate the C-max style driving by having seat up a fair bit, as it felt like it might work with it being a slightly taller car than the MK1 Leon but it didn't feel right and obviously the cars dashboard and pedal position aren't designed for that kind of posture, so I've had to accept a lower position very similar to how I drove mk1 in order for car to feel right.
To be fair it is actually far better how I've got it now and allows me to get the most feel and control out of the car even if it is not necessarily how I would prefer to have the seat set given a choice. Maybe I will be better off ordering a higher seating car again next time, but its my third Leon and I do have a massive soft spot for them!
