except for the occasionally reported tendency for the rear end to bounce when the car is going around a corner

Yeah, it looks like it's an issue with the sensitivity of the DSTC and hitting a manhole cover during a turn. (The DSTC is supposed to notice slippage of very small amounts -- 12 to 50 degrees, depending on who you ask -- so it's really intended to work that way, but it works against you in this instance.) There's another issue with the shift linkage cable, but it's really cosmetic only.

Hey, it's the first year of a new model. Oddness is to be expected, unfortunately. At least I got in on a model before Ford totally took over.
