If you're tall, that Kestrel for 300$ is a very good deal.
You'll probably want to upgrade (eventually) to 10 speed and brake-lever shifting (for another 500 or so, unless you find someone ditching after an upgrade), but the Kestrel carbon frame is pretty sweet. Nothing wrong with the set-up as it is, unless the front fork is broken rather than merely sporting chipped paint.
Sorry, but IMHO, that Kestrel is trash. It has been in accident heavy enough to tweek the front fork severely, so there is a good chance the frame is also damaged. All the components are old and probably worn. The wheels should be thrown in the trash also.
