I would take the tint off. Reason being is that you dont want anybody pre-judging your car because of how dark the tint is. When you put it online with pics some people may see how dark the tint is and think a "gangster" owned it or something so you may miss out on sales because of something you didnt even know about. Take the tint off and if the person wants to tint it they will anyway.

Kinda like a used car salesman walking out to talk to you with a huge gold chain on, gold bracelets and rings. You're going to prejudge him based on your observation but he may end up being a really cool guy to deal with.

 

OK, I think this topic has run its course.

We got some lessons on the English language and plenty of answers on the OP's question.
