Did you lease or buy to own?

Hello, Im interested in the CLA250 and it would be my first benz / luxury car. I noticed in pricing section, majority of you leased your CLA. I was wondering why is that? Is it better to lease a euro / luxury brand? Will maintenance on a benz be overly expensive after its 3-5yr (whatever it is) warranty?

I hope to hear did you lease or buy to own your new CLA? And why did you decide to go that route? Hopefully your opinion will help me decide the best route for me! thank you all!
