Hey! New to the forum so bear with me please... I'm just coming to the end of my 3 year Agility agreement on the new A-class (W176). I'm looking to buy the car outright by paying the balloon payment, but I'd like to see if I can get a few "upgrades" on the car - namely: 1. Rear parking sensors 2. Apple CarPlay. Has anyone done either of the above? Would you recommend doing via dealer? Any feedback would be much appreciated!!
