Arosa with 100hp or 75hp diesel?

Hi, I’m talking about getting me an Arosa. Year 2000. Now I don’t know if the 100hp super or the 75hp diesel is supposed to be. 126 are 195NM versus. 15tkm a year will be there. When do I notice this MORE of torque? In the acceleration of the fully packed car? Or on the mountain? Would that be grateful for the report. That the body is fully galvanized is already excellent. What about other diseases? Above all, there are reperatures such as tooth/keilri. emen?! After how much km do they have to be renewed? other cost-effective repertures? Thank you very much
