What's the reliabilty of a 99 STS??

I was looking at a 99 STS and it has 102K and I don't know how much he is asking for it, but I just looked at it. But my question is how reliable is the 99 STS? What is the average gas millage people get? Thanks in advance for replying.

The 99's were a good year. I get around 22-26 on the highway with my 2000 STS if I'm not into the throttle too much! :)
