Does it require modifying?
Yes please to a guide! You might have started something?
Straight fit just need to take care. Horn works, airbag light comes on and then goes off as it should and only cost £50 shipped to my door.
Can do my own guide or can rip one I found on a polo site that I read once for reference (this has pics)
Polo gti (mk5) one has red stitching and lupo one fits too apparently and mk3.5 cabby one fits if you can get one, so plenty of choice.
