Good evening all. I am new to this forum from Tampa Bay Florida. I am in need of some help prior to buying a 1983 Mercedes Benz 300SD. I went to go look at one the other day and it looked fine. Its a 1983 300SD with 133,000 2 owner car. no rust, straight body, coolant tank had no rust, leather had no rips, car started fine. Though there was a small little light on the dash that is a circle with 6 little hash marks around it. When pressing the brakes, this light would start to flicker. I looked it up and it said something about brake wear sensor light. Is this a major problem? Please help someone, as I am about to go buy this car tuesday morning for $2200. I included the link to the car below. Also the drivers side seat switch doesn't seem to be working, does it work off of vacuum or off of electricity? Does someone know where I can get a cheap used one that works?
