After the SLC years (code W107), Mercedes decided to take the next step by offering the ultimate coupe, a combination of racy four-door sedan and a great touring car. While respecting the tradition, the Stuttgart firm, as usual, offers some innovations. The tradition: the SEC takes the base of the W126, reducing the wheelbase by 10 cm, lowering the roof of the roof and lowering the center of gravity. On the innovation side, Mercedes (finally) launches into a serious aerodynamic study: grille and windshields more inclined, exterior mirrors redrawn in the same optics, and for the first time the side windows are flush and without amount. This big car, however, arrives at a favorable Cx of 0.34, result constituting a near record for a vehicle of this category. Unlike SLCs which offered two real places plus two extra, the habitability offers a comfortable four adults. Only the big cut Americans at the time can accommodate four large people in wheelchairs. Curiously, models that are sold in the domestic market are less well equipped than export models, but the number of options is plethoric! On the road these cars offer a healthy and balanced behavior, but requiring some caution on wet ground. But is this a handicap for this lady who certainly does not want to be pushed to its limits, especially given its impressive performances that are far from being sympathetic to our innumerable radars! And, whatever the look, the comfort is without reproach, quite comparable to the best achievements of the time. True TGV before the hour, the 500 SEC delivers an approval to the height of its reliability and its image, legendary qualities of the mark of Stuttgart.
