For spirited street and "occasional" highway driving a 3.55 would be good. I find myself driving 2-4+ hours to bigger shows. All the rest are local within a few min. drive time. I am 65 and really don't need to smoke the tires a city block with a big engine and a big gear. A 273/4 and a 318/2 do me fine. Besides , I get almost 20 mpg with either car and both have plenty of pep.
