O4's were never called "Limited" because only one model was available.
Actually, they came standard with one desirable feature that no other "Limited" ever offered, the self-dimming rear view mirror.
As for the price, all I can tell you is, some people paid sticker price+ and don't regret it. Other's have got the deal of a life time on brand new (never titled) Crossfires for as little as $17k.
It's summertime and that means peak "Sports Car" price time, especially for dealers. You can spend more time shopping and possibly find a better car, at a better price. Or wait until the snow flies and probably save $1000's.
The answer is simply how much can you afford, and how soon do you want the fun to begin.
I've owned more than a dozen "previously owned" manual transmission cars and I've never had to replace a clutch. If you don't trust your own judgement on any car that you're looking at, it's always a good idea to have it checked out by a mechanic with a good reputation. Good Luck!
By the way, my 04 has 48k miles on it, and I wouldn't take $13000.00 for it.
