Alfa Brera

[Raverbaby]

Hi folks,
I'm looking in to the Brera as being my next car, currently got a 2005 GT with 43k on the clock.
I saw This one It ticks all the right boxes, only thing i'm not 100% on is the wheels.
How much would one normally hope to knock off dealer prices?
I'd be trading in the GT and (hopefully) paying the rest cash, would the GT + £5.5k be a tad on the hopefull side?
I take it the irish plate isn't a cause for concern

Thanks.
