Remember, you can also argue the point of the Euro lux being 17's, thus you can theoretically go to 19's if you wanted, but it would have to be a 19x8 but im not to sure on the intreprtation of that rule so to be safe a 18x7.5 should be fine
The problem with this is that the luxury version (according to a previous thread I remember) actually uses different suspension components to allow for the bigger wheels to start with...

If you have a standard Euro, if they wanted to difficult as insurance companies can be (note: if you do an online quote with AAMI you actually select Euro or Euro Luxury so they know what size wheels it comes with!) they'll work from the fact that you have 16x6.5.
