You have a very nice car! Guaranteed it would not drive out my life they are closely matched, in fact on paper equals 1/4 mile et’s. The older SRT’s are slower than yours. The 17’ you have would be a close race to mine car. Looks are subjective. The challenger is nice, I’ve driven them, but the Mustang a better all around car especially when Overall Value is considered and without that massive blind spot over your shoulder..
The challengers have become stupid expensive for no real reason. It’s just a portly dodge after all.
