I am looking at a 2002 aprilia 150 scarabe scooter with 1100 miles for $2500 dollars. It has top and side cases and is in great condition. Is this a resonable price? Are there any know problems with these? Are parts easy to get? How many MPG should I get on it? I own a gs and used to ride mopeds but haven't been on a scooter in 25 years. The transmission on it looks simular to others I have seen are some of them universal? Do they have problems? Sorry for all the questions but this looks like the perfect scooter(at least my idea of one) and I would like to snap it up if it is worth it.
