The Classic is still a very new model so there doesn't appear to be many who have test ridden them yet. I found one review of the scooter - http://www.scootersales.com.au/News-2416-sym-classic-50-125.aspx Actually... on second thoughts try searching for the name that the scooter is known by in other countries - Fiddle ii
The only thing I can suggest is that you demand a quote of the on road price inclusive of 12 months registration, stamp duty, dealer delivery to do a real comparison with other scooters.
Also try the Piaggio Fly & Daelim S1.
Stay away from mainland Chinese scooters if you can afford to do so.
Still, if you heart is with Vespa then chat with Steve at Ace Scooters about a secondhand but barely used LX150 that is currently sitting in his showroom.
