Looking to sell my 2 month old Vespa/Scooter ASAP

My parents recently sent me my car and I no longer need the scooter I bought this summer. It has less than 450 miles on it, it is still under warranty (1 year) and quite frankly I just need to get rid of it. I am selling it for the best offer. It has a clean title, comes with a helmet, and is already registered. It gets around 120-140 MPH and has a 150cc engine (which means you can drive it on the highway if you want). It is virtually new. I used it very infrequently this summer, but its a really nice scooter and very fun to drive around Palo Alto, SF, and Stanford. I'm willing to let it go for around 700, but we can negotiate. I want to get rid of it ASAP. Thanks.
