Moving to Dakar

Hello!

I am moving to Dakar in a few months for work and I am trying to plan my move as much as I can.
I was wondering if you could help me with a few things:

What is the average cost of living in Dakar (excluding rent), for comfortable lifestyle: eating out once or twice a week, doing activities such as surf/gym, going out once or twice a week, maybe go to a nice restaurant once in a while, etc - nothing extravagant, just a comfortable lifestyle

How much does it cost to have a car? I saw a few prices for buying a car, but how much would it cost to maintain it (gas, insurance, etc) - also do you recommend a car? I know traffic is a bit insane, but I was adviced to get a car regardless (I have no problem driving in traffic heavy cities)

Where should I live as an expat? Right now Mamelles and Almadies would be my top picks, but do you have any other recommendations?

I see that unfurnished apartments seem easier to find, how much would it cost to furnish? Just to have an idea

And finally, how does rent work in Dakar? Does it go up every year? Is it stable? Can the landlord increase rent?

Thank you very much for taking the time I really appreciate it!
Cheers!
