We used to call it 60-80. You could buy a two-year-old used car with 80 percent of it’s life left for 60 percent of the new car price. Then, as Detroit & Co. started to overproduce ad nauseam, the ratio went down to 50/80. Then 40/80. These days you can pretty much buy a decent two-year-old car (think discontinued Ford, Mercury & Buick models) for about 35 percent of it’s new car price without dickering too hard. So, is that the sweet spot in today’s market? Nope. At least not for the non-enthusiast. The biggest bang for your buck lingers a little further down the curve. Specifically the five to six-year-old commuter vehicle with about 75k miles that has become as popular as an old can of buckwheat. Think Ford Taurus, Buick Regal/Century/LeSabre, Mercury Sable and virtually anything with the name Oldsmobile on it. Sure these are the equivalent of leisure suits for the self-effacing car snob. But I’d be damned if they aren’t the best deals for those who, in Rhett Butler-speak, “Frankly, don’t give a damn.”
