Here are a few photos showing my situation. Note that the car is backed almost all the way to the back wall, hence why the perspective makes it look like there is more available space than what it actually is.
I've measured the minimum with of the entrance, where the door frames are, to be 220 cm (86.6 inches) and the car is about 204 cm (80.3 inches) from one door mirror to the other door mirror (while open), so I have around 8 cm (3 inches) on each side with the door mirrors open.
The second photo shows a bit better the slope I have to drive back when parking and forward when getting out. It is certainly possible, but it is quite frightening to me.
That is what I tried first time and I ended up falling back and almost hitting the walls behind me. The ramp slope is too much for the car to creep forward, at least while setup in Normal mode.
