From what I've read, 88 dB is about average sensitivity for a sub. Is that right? But I've seen subs rated at 92 dB and higher, although for at least one specific model, a forum post I read (not necessarily this forum) said the rating was BS because the manufacturer measured it including "cabin gain". How many others do that, I don't know.
Should I be expecting to find subs with a similar sensitivity to my other car speakers (92 dB,) or is less OK?
Some Kenwoods I just found on ebay are rated between 91 - 93 dB. Any opinions on Kenwood subs?

I wouldn't worry about the sensitivity all that much since cabin gain is usually a bigger factor anyway.
The kenwood Excelon range is pretty good, don't get the entry level subs since they have a higher Q and tend to sound boomy.

Agreed, cabin gain is going to account for a lot in the small confines of a car. so 85-90dB is generally sufficient. The main advantage to higher sensitivity is less distortion, both speaker and amp generated, and horn-loading is the only way to get very high sensitivity. I'll have a horn loaded sub or two suitable for autos appearing on my site over the next few months.
my corner horn F3-40hz horn functioned well in the car,126db with 20watt input at 50hz
Bear in mind the driver was a US$9 8" unit which probably suffered from 10db power compression at its 20w rms rating
