First hand I would go with the Mustang between those two cars. Think about it in a couple of years. What will look better and draw more attention. A mustang or a Srt-4. I would go with the Mustang hands down wouldnt even think about it (i like mustangs hahaha). But I think you should take a look at the GTO. Like stated above you know what you need as a DD and get what best suits your driving needs.
Mustang......classic
