George,
If you have your heart set on an Aventador...and if we have established that there is not one in Europe...and any available body is $10,000 and the EVA is as high as 25%...that extra $2,500 seems kind of trivial in the big scheme of this project. Also, consider that even if there is one in Europe and the quality is not as good, you will go through $2,500 in no time trying to prep it for paint.
