(S) WHEELS for GP 1.3 JTD 75hp

Hello Fiat Fans and Owners,

Besides Fiat co. wheels offer ,which are the best match light alloy wheels for GP 1.3 jtd 75hp on the European market ?Is there available BBS option ? And about size 15" vs 16" vs 17" Since I do not know much about cars I wonder what will be the efect of fitting 17 inch wheels on mentioned GP model?
Just more diesel consumption ,maybe a little bit slower than with15"?

I will appreciate your response
Thank's

Get some 17's on !. All other sizes look too small, unless you slam it on it's arse!!. I had 15's on mine from new, i changed to 17's and there is no difference in apart from it handles slightly better.
