Not sure what this means..Fiat changing platform on products

You guys realize the FWD/AWD/RWD LH/LX platform (Charger/Challenger/300/Magnum) was an AMC/Eagle design and has been in use since the 1980's and was also the platform for Intrepids Concords and Visions, right?

After some searching i stand corrected, I have always heard it was a mercedes platform, it just shared alot from a Mercedes. But I still like what they are doing, yes the dart could have been better but all manufacturers have hit or miss cars also look at the caliber, they should have redesigned the neon over this one.
