When I bought my 300D Turbo ('84), I looked through the records and apparently a block heater had been installed. I looked under the grill and I can see what looks like an outlet, but the car didn't come with a cord. Can I get one of these off of Fastlane? Also, my car runs pretty cold during the winter, rarely getting between 40 and 80 on the gauge. If I heat it up before hand, will it run warmer?
