You come in from the right? 70cm passage width is quite tight if there is a wall on one side. That is less than the width of a normal door passage. You must not hang anything on the walls, otherwise it will not be enough. No winter tires, ladder, etc. Also, this assumes that you always park well. Once 20cm too far forward and your pants get dirty.
Does a car have a trailer hitch? Then you can easily add 30cm extra to the length.
What do you do when you have luggage? Groceries, sports bag, something like that. Carry it once around the garage or unload in front of the garage and carry it through?
I see two ways to improve this:
1. Close the garage completely on the right and always enter through the left gate. Then you can also hang something on the wall if you want. But you always have to walk around the garage.
2. Replace the garage with a carport. Since you have no walls, 20cm in front and back are not critical. Possibly the saved square meters can then also be used for a little more width.
