I had 17s,
they make the car sit far too high off the floor,
also they swamp the breaks making them look tiny!! not a good look
as for the choice on wheels, you're defs onto a loser on this site,
cliosport isnt into larey wheels, more subtle wheels ftw!!
personally id keep an eye on the for sale section for a nice set of second hand wheels,
might even get a set of turini's for £450!
or at least some OZ F1s, stick with the OEM+ look, youll be greatful you did! (i went off my 17s after a year, binned them and bought some 15s. car trends change, OEM+ will stay the same, big wheels are very 200*'s! lol)
and i defs saw a set of white supperlageras go on there for around the 450 mark!
basically what im saying is, go second hand if your budget isnt good enough,
just make sure theyve been well looked after!
