6N front wing replacement. Do pattern ones fit OK?

I've got to get a replacement o/s/f wing for My Girlfriend's Polo as it's got a rather large dent in it! Just interested to know how well pattern replacements fit as a genuine one is about £95, over double what I can get one from Bucks Car Panels.

Am I OK to get a pattern replacement without too many fitment worries or am I better off getting hold of a second hand genuine job?

Thanks in advance, Ash
