So I just got a job with a Courier company and will be using my 93 960 as a delivery vehicle for 5 hrs a day 3 days a week. For the time I have owned this car, I have done about 95% highway driving. Now it seems I will be doing about 95% city driving. I maintain my car very well, and keep up on everything, but I still wonder how it is going to do with this type of "brutal" driving; stop and go, on and off, hard acceleration from time to time, and in about 2 months time, snow and extreme cold. Anyone have any tips as to how I can keep her running strong?
