as title just wanted to know if it would bolt straight on as ibiza's and polo's are almost the same thing

No it won't, completely different shaped front if you actually look at it lol, the ibiza is much squarer.

Polo Classic/estate/caddy bumpers can be made to fit the Ibiza, but only 6n polo bumpers will fit a 6n polo.

Go for a valver bumper, much nicer looking anyway.

the 8v bumpers will fit from the ibiza onto the 6n but needs a couple of inches removing from the middle since the ibiza is slightly wider than the 6n :) thats what I was told when I asked on their forums :)

Thats bullshit as well, the 8v and 16v bumpers are exactly the same.

Basically anything will fit, but it won't go straight on, will need quite a lot of modding and its not worth it when a 16v polo bumper is much better looking.
