Neither Fiat/Chrysler cars(Dodge is a Chrysler)  are the worst production cars on the planet. You'd be better off setting the money you would spend on one on fire because at least it wouldn't cause you anymore problems after that.  

They're both made by the same parent company. 
Scotty wouldn't be a fan of either one. 

Run away.

Do not waste your money on either.

neither - both are terrible cars relative to their class and price point. Chrysler 300 is big, bad on gas, low on power, its antiquated suspension is stiff.

Charger guzzles to provide effect / aesthetic. You would look way cooler in a Camry TBH - and Camry is straight line faster, sharper on the corners than bother of these boats

300's are notoriously overpriced in used car lots, and by their owners. Chargers are notoriously beat on by college kids and road ragers... idk man i'd be like what's my price? and how much more will it cost for an Accord or Camry? Even a Chevy Malibu might be better if you must go USA.
