I think I am going to give this a shot. I guess the next questions are:
1. Whether to get the Crosstrek's cladding parts or whether to emulate it with something else
2. Where to get the Crosstrek's cladding parts (a quick search and I haven't found anything yet. Not unexpected given how new the model is.)
3. If I don't use the Crosstrek parts, what to use instead.
I'll do some more looking around. Of course, thoughts or suggestions are always welcome!
