The 2.7's are a nighmare for thousands of folks. All you need to do is some simple searching. A design flaw keeps the 2.7's from holding up as they become full of sludge after only a few thousand miles in many cases. Folks who use synthetic or are LUCKY can get 100K+, but not many. Check and you will see a lot with <50-60K, and still owing big bucks on them. No wonder they can't hold value. The oil does not flow well and will "cook" in various parts of the motor and turns to sludge. Does not matter even if you change oil regularly. You can find a lot of information on this site too. 3.2's are AOK, but not 2.7's. The Intrepids also have steering issues, but I have not had any as of yet. The racks tend to wear out I understand and a lot of folks think they have a design flaw as well. The fact is that there are issues, espscially the motor, which is an easy 6K to replace. You cannot find a used one <2K, and these are usually junk. I hear that newer ones are improved, but who knows?
