Buying a Magnum, What do I Look for?

My wife has a 06 Magnum that she uses as a daily driver.
She loves the car and there are damn few of them out there.
But.........
I've had to replace control arms, lateral links, ball joints and sway bar links.
The gearshift in the console had a plastic part that broke and wouldn't allow the car to come out of park, replaced that. It wasn't hard just a PIA. Also I had to replace the lock cylinder.
The right rear wheel opening is prone to rust. I've seen several with that issue in the same place.
I've also gone through several sets of brake pads and rotors (but to be fair, my wife is hard on brakes).
The car has a lot of room and is nice on road trips. She's got damn near 200K on it and it seems to be holding up well. It's a 3.5L and not 5.7L. The 5.7's are known to crap out cams.
