GREENVILLE, S.C. — The only thing that would prevent me from buying the 2019 Mercedes-Benz E450 4Matic Wagon is its $65,195 price tag. Or, in the case of the press loaner E450 Mercedes recently left in my driveway, $88,535. It's simply out of my budget. I do find wagons irresistibly appealing. Furthermore, I find wagons with some serious gusto beneath their hoods even more appealing. Dear Dodge: Please bring back the Magnum SRT Wagon.
