Aside from the extra (tiny) rear seats in the 210, is there really anything that differentiates these two in terms of performance and operating cost? I understand the history fine. Back in the early 60s the 210 was the step up from a straight leg 182. But in the late 70s the 182RG seemed to fill almost exactly the same role (unless you wanted pressurization). So looking at the used market today it would seem that either could work. Not that I am in the market for a plane right now, but if someone were looking to incrementally upgrade from a straight leg 182 which route would you take and why?
