Welcome to CT and belated congrats on the black R/T, John! I have
to agree that it's a great car and color...
And I originally missed your intro because I hardly check out this section, but after interacting with you on the forum I thought that you deserved a proper welcome. Good to have you here.
The other muscle cars are for kids, plain and simple. They do have strong points, but it's mostly about performance and it comes mostly from their smaller size and lighter weight, again, being kids' cars and all.
I don't meant to put down the GT, mind you, I know it's very respectable, but for someone who doesn't race and has enough years on the planet to appreciate quality, comfort and practicality... there's no contest. The Challenger is the thinking man's, or the gentleman's, muscle car. They can have their tenths in the quarter and fractions of G's .
And when the original muscle cars mean something else to you that some old school rides that an Accord can smoke, a good look at the Challenger will seal the deal. It evokes so much of that American styling of the late '60s - early '70s, when it was at its peak. The fact that the car is based on a Mercedes platform helps explain why it can feel so refined while Dodge has never been synonymous with quality. It's a man's car, as I said. You chose wisely.
As for the forum I think that you'd benefit greatly from lurking and exploring some more, figuring out who posts what and in what section to ask questions. Takes a while to get a handle on forums, especially when not used to them, and being new opens you to unnecessary attacks. Not that it's not a friendly and mature forum (it is), but we get our share of smartasses, pesky kids and people who think they are moderators, like everywhere else. It can be part of the fun.
Again, a warm welcome from (mostly) sunny LA!
