Also in the 500 Series was the 500 SEL which was a four-door sedan also with seating for five. The cost of the SEC was $56,800 while the SEL cost $51,200. The 500 SEC was the most expensive Mercedes-Benz in 1984 and 1985. Standard equipment included an anti-theft alarm and outside temperature sensor. Anti-lock brakes became standard in 1985, along with heated outside mirrors and eclectically-adjustable headrests. By Daniel Vaughan | Sep 2007
