Easy things to repair these so dont be scared ,chassis number is in the boot under something but some models vary .you cant do a lot with this vehicle yourself as its all encrypted software ,dealer only so you cant evan change the oil or the brake pads yourself as the immobiliser cuts in but apart from this small issue these are great cars for an urban enviroment and easy parking.with merc technology they last forever.But then all modern cars are going this way with regards to software so in ten years time their will not be any general garages just main dealers
