Haha I like the Chinease lookalike, probably drives better too =)
Mustangs were never and have never been designed for handling in mind, it's always been meant as a cheap way for people to get a 'performance icon'. They are overweight, underpowered, live axle pieces of cheap thrills. (don't tell that to a mustang owner!)
You can get independent rear suspension and some after market companies take new cars and put one on (IE Cobra) but then the cost goes up and your better off with the Camaro.
Challenger has a nice lump with the SRT8 but weighs over 2ton... so even with it's independent suspension it isn't capable of much.
They are all heavier than they should be, but they are muscle cars, or mullet cars depending on who you talk to.
I donno if I like the fastback styling they went with on the Mustang. Camaro and Challenger are nice though.
