Old Benz reliable enough for me?

[cstamm]

Here is my dilemma. I do IT field work for a living, drive anywhere from 500 to 1000 plus miles a week. I need a reliable car that won't leave me sit. I have long been interested in doing BD, and these look like good candidates. If I can find an early to mid 80's Benz that checks out good ad has good service records, do you think it will fit the bill? I get paid mileage so cost of fuel and cost to operate is huge to me. I could get a little Japanese 4 cyl car, but I just don't see the appeal. So, in your opinions, how will an old Benz fair with this day to day torture? Anyone have any sugestions on what to drive otherwise? Sorry for the length, thanks ahead of time.
