If you want a portable boom box for your Vespa look no further than here. I don't see us getting it anytime soon. In fact, I don't see us getting anything else for the scooter itself except for maybe the European tail light.
I haven't gotten to 400 miles yet, but I'm trying to drive the Vespa as often as I can. It has been raining a lot in San Jose lately which doesn't make it conducive to ride. Hopefully I'll get to take it to work on Thursday and Friday.
