Purchasing advice please

Yeah, I understand about checking out the car thoroughly before purchasing (carfax inlcuded) but what's the matter with buying used?? I've got no problems with it as long as the car is clean. I won't buy rental cars, salvage titles, or anything similar. But a car like this one looks clean. Carfax checks out beautifully.

Still...the price is bit high. Within KBB with that package (and for a certified PO) apparently, but still seems high to me. I will go to check it out, but would only buy it if:
a) they give me a good price on my trade in
b) the price comes down by a few thousand

Meanwhile, anybody recommend a dealer with good pricing around the TriState area?? Or just on the east coast??

Thanks for the help and opinions! I really appreciate it!
