On the valve seat, do you (or anyone else) know if that's an early 5.7 problem? I was reading that they updated the engine in 09 with variable cam timing and modified the heads, and I've heard it's not uncommon for them to drop valve seats, which I would really like to avoid. So if I can't find a Magnum, I'm leaning towards an 09 or later Charger because of the updated engine.
After I test drove a Charger, I was in love. It's as easy to drive and keep lane center in as my mom's Jetta, but it feels much more solid and obviously it just makes great power. Definitely excited to get into the LX platform.
