I also leased a 2017 C43 AMG W/ 4Matic. I got the car December 2016.
I believe the MSRP was right around the 60k mark. (don’t remember exactly from over a year ago)
I pay $595 for 39 months, with auto pay and 3 years scheduled maintenance included.
$0 cap cost reduction, down payment, was taxes (NY state), 1st month and bank fee.
12,000 miles per year. This is my 4th Mercedes and more then I was paying for my 2012 E350 4-MATIC.
Love the car, hope you do too!
