With few exceptions, the performance of these five sport sedans is covered by mere tenths of a second or a few miles per hour.
The BMW's acceleration, as usual, is striking, while the Cadillac lags behind considerably. Handling numbers, however, are a virtual wash among all the contenders.
This leaves the decision-making to more subjective means and personal taste, which is ultimately what most buyers rely upon in any case. The fact is, all five of these sedans are excellent cars. And it's not hard to find reasons to buy any of them.
We simply find the Infiniti's combination of engaging driving character, high feature content and low cost to be the most appealing. Plus, all great performances must come to an end sometime.
