Hi Mate,
What S1RST and Matcos say is spot on. If you are looking for a good car with less than 30k, I would suggest that you should be looking to spend 15k or more.
As for problems to look out for, there is a thread somewhere on here that I used when i bought mine. If I find it I will stick the link up for you.
lastly, if you need to know how an EscCos should look, inside, outside underneath or anywhere for that matter check out Matcos's concourse preparation thread. It is excellent, and I will be using it whenever I do any work on my EscCos.
i hope this helps.
