Cup spoilers

Hello, I'm going to look at a car Friday, it doesn't have a cup spoiler but I really wanted it to have one, I'm going to have to get this done separately, does anyone know how I can sort this out, will I just have to take in into a Renault main dealer?
 
Or find one second hand. They simply are held to the boot lid with 2 screws (you will have to drill holes in the correct position) I'd imagine any local garage would fit it for you for next to nothing if you don't feel confident fitting yourself.
 
The car I'm viewing doesn't have a spoiler at all so I think I'm safe there, thanks for the link rsevo but can't seem to get anything up?
 
Just looked again it does have gt spoiler, pictures aren't clear, if worst come to worst ill swap spoilers and boot lids (just done my revision) with someone on here and maybe give them some cash, see how it plans out
