This one is a private sale - being sold by the same chap I bought mine from.

2006 CHRYSLER CROSSFIRE SRT-6 Supercharged AUTO BLUE | eBay

In my experience, he's s traight guy to deal with - has a bit of a thing about SRTs - I think he just can't resist a nice one when he sees it but can't justify keeping them all - when I bought mine, he had two virtually identical black ones!
Still got it over a year and 3500 miles later - very pleased.
I think the reason this one's been on & off is that he's been messed about by time wasters and won't haggle much - he's not afraid to set his price and stick to his guns - so don't expect a give-away bargain.
But if my experience is anything to go by, it will be a good 'un - he doesn't buy rubbish - definitely worth checking out if you're serious but don't delay.
And no, I'm not on commission!
