I do like the retro Mustang but I don't care for the Camero. It just is not retro enough for me. I think the Challenger would fit a family much better as it has a larger trunk and way more room in the cabin. I don't race anymore. Did plenty of that in the 60's and 70's. I'll leave that to the younger crowd. I do like to have fun though so we went with an R/T. I didn't think the 10K extra was worth it for an SRT. In the end I guess only you and your wife can answer your question. If you can swing owning both then go that route. If not then I think I'd trade for the Challenger in what ever trim level you're comfortable with. Just my .02
