Going with the 2012 Nissan Xterra? Watch the powertrain and airbags. The 2012 Mercedes-Benz S-Class has fewer reports in those categories, so you'd be trading one set of weak spots for another.
On the dollars-and-cents side, total repair exposure across the top problem areas runs 2.7x higher on the 2012 Nissan Xterra. That's the number to keep in mind when you're pricing the deal — a $2,000 difference in purchase price disappears the first time you're staring at a transmission rebuild.
