I used to own an '01 SE intrepid with the 2.7L and I didn't have any issues with the engine at all. I did have to replace the tranny at 95,000 miles but other than that it was the perfect car. It got totaled by a drunk driver at 125,000 miles and I decided to replace it with another Intrepid. which I have now and it is even better. It is an '01 ES with the 3.2L fully loaded which i would recommend to anyone, the ride is so smooth and the size is great. The only advice I have if you are thinking about getting an 1998-2004 Intrepid is even though had no issues at with with my 2.7L engine, you should look for an Intrepid with 3.2L,3.5,or 3.5HO engine.
Moonroof, the smooth ride, and the overall look of the whole car.
The company needs to recall the older 2.7L engines and replace them with 3.2L engines. Other than that this is a great car and enjoy the ride!
