I really like it but remember this is my first ever bike, it would have to be really bad for me not to like it
I think commuting is the major strength of any maxi-scoot. Lots of storage and protection from the elements plus the convenience of twist-n-go, perfect for riding in traffic. The third wheel of the MP3 gives you greater stability in less than ideal conditions (a third wheel means 50% more rubber on the ground). Plus 2 disk brakes up front means it stops quickly too.
Negatives are the cost. For some reasons maxi-scoots are freaking expensive compared to bikes. The build quality is not the greatest on Piaggio (typical Italian you might say). I’ve not had any major issues (just a few minor ones) but the support you get from Piaggio is really poor. You are relying on having a good dealership to sort you out, you will not get any support from Piaggio. They are trying to increase their reach into America so they are letting almost anyone sell their product. I would not buy one unless I knew I had a local dealer with a good mechanics.
Other scoots to consider are the Suzuki Burgman and the Honda Silverwing. They get good reviews from owners. There is also the very sexy Yamaha TMAX which looks (almost) like a sportbike.
