I initially bought a 50cc to save money (no insurance, no tags, no license). It
really was to save money, as we gave our 15 year old car to our 16 year old son to drive to school, etc. My husband and I share the second car now. I've since upgraded to a GT200 for the fun factor, but it's still way cheaper than buying another car.
That's my story and I'm sticking to it!
