Welcome to the site. Not everyone here owns a Challenger, so dreamers definitely are welcome (I am one myself, and nobody has given me a hard time about it).
If you're dreaming though, grab the SRT for your fantasy garage. In real life, I woud buy and R/T just b/c of price reasons, but it's easier to get the classic stripe/wheel package added on after the purchase than to add the power and suspension upgrades of the SRT.
