Bought this car when I joined the Air Force and it has been very reliable. I have driving across country three times and have never had a problem. The only down fall is that the car takes premium fuel only and it costs me 50 dollars to fill up. Was very easy to find performance parts for, and the car handles them very well.
I bought this car in 2006, it had around 45k on it. I drove the car for about 100k miles when I owned it. First, the car says to run premium only but I never did. I ran regular in it the entire time and it never gave me any issues. Issues with car: Replaced 02 sensor, transmission was making a clicking noise, but never gave me any issues. Sunroof gave me trouble with jumping, jerking, really rough to open. I just stopped using it soon after buying it. Back hatch would not stay up when opened. Dash is cheap, it was cracked when I bought it. Wasn't starting well, I didn't want to deal with any longer so I sold it. Glad I owned it, good car and low maintenance.
I've had my Eclipse for just over two years now and wouldn't trade it for anything. It is sporty , dependable AND fun. No problems whatsoever with this car. Test drove about every other sportscar in its comparable price range before deciding on the Eclipse. Nothing else came close. Smooth handling/ride, no shimmy, no shakes.
This is not a car for beginners and shorter folks. The gas mileage is decent usually 20-25 mpg, if you want v6 power you get v6 mileage. Make sure you understand repair cost if you decide to purchase this car for the long run. For instance timing belt is usually $300-500 depending on where you get it done and the MAF sensor is between $110-625 depending on where you go. It does take time to get used to seeing properly. If you are a good driver it'll take about a week. The car does understeer and takes some time to get use to but it can take bumps and bad roads fairly well.
