Hi all from Sweden

I've been looking to buy an used car within a year and the 500L caught my eye because of the price and size.

I am 197cm (6'5) tall so I do have some concerns about the optional sunroof.
Is it the same height inside on all 500L models and year editions or do they differ?

I'm probably buying a 2014 or 2015 edition if I were to buy one. But would it be the same height inside if I tried a new model like 2017?
Reason is there isn't many older 500L with sunroof around and I'd like to see if it's possible for me to fit inside one with a sunroof as several people says it lowers the ceiling height.
I sat in a regular 2016 edition yesterday and it was a tight fit in the back so anything lower will get a bit tricky..
