What spoiler for my 2009 mk3 clio?

Hi, I've got a black 2009 mk3 Clio Extreme and I'm looking to get a small spoiler for it as the rear just doesn't look right without one. I've been looking at ones similar to this:https://www.ebay.co.uk/itm/204615707761?_trksid=p4375194.c101959.m146925
However, I would have to paint it and also with ones similar to this they are either mounted by glue or by drilling into the car.
Does anyone know where to get a spoiler like this and if its difficult to install etc as this is my first car. Thanks

i got a bootlid from a GT from the scrappy for £50, quite a bit of later mk3s had the GT spoiler fitted from the factory so if you keep your eye on ebay you will come across them now and again
