welcome to the site. i am relatively new to the site also but have owned a 2.7 liter 2000 intrepid since june 2003.
some of my problems have been weather strips around the door shrinking, fuel gauge and power steering pump went out. also, most people seem to have problems with their driver's window coming off track and/or making noises. some people don't think much of the 2.7 engine but mine has been great so far.
i bought an extended warranty with my car and everything has been covered by it.
also, look in the second gen forums and ask questions. the people on this site are friendly, will answer questions and seem to be extremely knowledgable (sp) of these cars.
there are a couple of members from your area, i can't think of their user id's off hand, so you may want to ask them questions especially about price and dealers in your area.
