A leakdown/compression test was a good thing to get done with the 08's if you were having problems. Not sure if the 09's are having the same problems with the ringlands or if it's something else now. I don't think the dealer should be selling a car as "new" with 124 miles. I think either someone bought it and traded it in or it was used as the test drive car. Either way, that's a lot of miles for a new car IMO. Talk them down and have them run some tests.
