As far as Pro's and Con's...
Pro's... they take a lot of abuse and are easy to mod
Con's... no fast speed quick lane changes. The ass end will get around you. Hence why there's a lot of wrecked/totaled SRT-4's.
To me, there's a lot more pro's then there are con's...
I've only ran into one problem which was fixed within a week. Other then that the car has been great!
