Just bought my 05 LGT with 214k on the clock a couple weeks ago. Turns out the "valve cover leak" it appeared to be was actually cam seals... $1400 later I learned that the timing belt was already rubbing so at least I didn't risk the biscuit and blow the motor...
Overall I'm happy with the car considering I don't have that much in it and it's in fair shape. Wish I had spent $12k buying one in better shape, but I didn't have $12k to buy a car...
