rfitz, welcome to AO.com and from another fellow Irish GT owner
The Q2 is not down as any available option on any new model over here which is a shame, however if you are thinking of buying new it might be better & cheaper for you to buy a UK car and import and have it all done for you at the factory
I have a feeling Gerry Campbell does the Q2 upgrade, so might be worth giving him a call. Also, try logging into
AlfaIreland
It's a new site and new Alfa owners are always welcome
This thread might also suit you on boards...Irish guy looking for a GT circa same year as yours
You might also get in touch with CCOVICH on here. I was talking to him the other day and he was mentioning the Q2 for his so maybe he has some info on who & prices.
I'd be interested in getting it done myself but wonder what the implications would be for the warranty of it wasn't done by the dealer?
