GT 16" wheel compatibility

Need a little help.

I'm about to upgrade from 16" to 17" wheels on my GT and I want to sell on my existing wheels.

Can anyone out there tell me which other Alfas, or even Fiat's the wheels will fit so that I can properly list them on ebay?

I am also open to offers on the wheels. They have done 11,500 miles (05 car) and are mint. No kerbing of any kind and perfect, dead even light tread wear. I get no wheel shudders from them, like some other GT drivers seem to get. They have been cleaned weekly and have no brake dust tarnishing. Tyres are Dunlop SP Sport 2000 205/55/16's

Cheers.

The 16" are fine on a GT/147/156.
They will also fit a GTV/Spider but will need a spacer to get the correct offset The GTV/Spider use 205/50R16 tyres though.

Cheers.

Another week to wait for the 17's, then they'll be on the bay.

If you don't mind me asking, where are you getting the 17's from and how much are they? Thinking of doing the same with mine.
Cheers.
