Good find - I had to take a second look as an SRT6 exactly like yours was shipped from here in NZ to AUS for a dealer , I should have written down the Vin # . My SRT6 Roadster is also an '06 build, it makes you wonder if we here in Australasia may have ended up with the last run outs ?

Anyway, if it is anything like mine ( also purchased brand new ) then wait till you get around 8k on the clock, they seem to loosen up and really start pulling hard - lock it in 1st and turn the traction control off, stamp on the gas and hang on - its addictive so be warned

All the best my Aussie friend
