Thinking of buying a 5.7 Dodge Magnum

I have owned 3 lx vehicles and I currently own 3, 5.7 hemis. Great platform, and great engine. Oldest one has 180k miles. Never an issue.
The the only issue I ever hear, which I believe to be greatly overplayed is valve seats. As long as you don't overheat it, shouldn't ever have a problem.
