I'd say $3k. I just sold an 05 4wd EX w/150k and with none of the issues you describe on yours for $5500, and it appears that is on the low side for that model/package/mileage. The 5mt and 2wd are the main things that lower the value, IMHO. The rest of the stuff is mainly maintenance/labor that can be put-off for a while, or until the car finally dies. If you list it at $3500 and take offers, I think it will sell quickly and you can feel good about selling "as-is."
