I have actually seen one of those wagons around. There is one in my area. I live in Calgary now.
I'll keep my eyes peeled and let you know if one pops up. Alberta and bc is the best for finding good German cars.
As for mods I am reluctant right now because I have a good warranty for a few years still. Dinan stage one, intake, exhaust and rims are what I'm looking at right now.
