You probably need to put some more thought into your requirements,
though sometimes window shopping the variety of what is available can
help with that thought process.

Some of the questions you should be thinking about:

- Are you making one or two for yourself, for a proof of concept
prototype, or are you beginning what will be a production design?

- How complicated is your task?   Do you plan to write most everything
from scratch, or leverage an existing code base?

- Do you need to be able PC compatible?   At binary level, source
level keeping same operating system calls, or just having comparable
services such that it's generally possible to write a program that can
be tested on a PC and also compiled with some moderate #ifdef'ing to
work on your embedded board.

- Do you have real time requirements?  If so, what kind of latency can
you tolerate?

- What kind of external I/O do you need?   A/D's? CAN? RS232?  Wifi?
Bluetooth?  Relay drivers?

- What are you willing to spend on development tools, both hardware
and software, and what kind of portability restrictions (dongles or
host locking) will you accept on compilers?   I have one embedded chip
that requires a $1200 programmer ($1800 if your laptop only has USB),
another that uses GCC and a serial port (jtag is possible but I have
never needed it as the mask boot rom understands serial), and does
work with a USB/serial converter too.

- What others have already pointed out about vehicle power supplies &
termperature

If you don't know what you need, then it doesn't matter for you which 
board to take.

Then maybe you shouldn't be looking for such a thing.  If you don't know 
what you want even well enough to know the names people usually call it, 
odds are practically zero you'll find it.  And even those minuscule odds 
are ruined by you giving people not even a hint of a clue what it 
actually is you're looking for.

For all you've told us, every single one of the several dozens of 
embedded electronic boards in a typical current car, from a dumb slave 
unit driving hardly more than a couple of buttons and lights, to the 
high-power do-it-all processor sitting in a high-end central 
entertainment/navigation/display unit, would qualify.  But they're all 
quite completely different, so which of them could you possibly be 
looking for?

There is no such thing as "the" best of anything, be that manufacturers 
or embedded board.  If there were, all the others would not exist.

Don't know whether You are aware of the fact that the power supply in a 
car is very &#4294967295;dirty&#4294967295;, the board You want to install will have to able to 
handle that (so specifically designed for vehicle use), otherwise You 
will have to construct filtering stuff Yourself.

Good luck!

Yours sincerely,
Rene

For vehicle computers, you should include "temperature range" as one
additional search phrase, since some boards have quite limited
temperature range and thus must be discarded in an early phase of a
search. 

Power dissipation is also an issue, since in such environment, fanless
operation is preferable.

In an environment with lots of vibration, look for the mechanical
ruggedness of the whole system. For instance, the PC/104 boards can be
firmly stacked together.

embedded PC or embedded computer are OK, you might try M2M, or strings
containing 'low power' , 'small form factor', PC 104,  etc.

check out www.winsystems.com too.

I suggest u that keyword, "sbc".
I'm working for it, that's great.
