One lady's pump went out like that at the Dragon two years ago - Chuk changed it in the parking lot with minimal tools. At that point, I made up my mind that the car is just not that hard to work on.
I changed my belt tensioner and idler pulley in just over 45 minutes. And oil changes on these cars are easier than on any four wheel vehicle I've owned.
As to your oil leak, I've owned three Crossfires, never had the issue. My newest car, an '07 with 28000 miles, is leaking like a rusty pail. I ordered gaskets and bolts from Rob and will be yanking the covers off and doing it myself. Looks like the "1 out of 3 have the oil leak" theory holds water, at least for me. I've also had to put two alternators on this car already - but I'm still gonna have a forth Crossfire - my next one will be an SRT6.
