My DH has a Pride Victory 10 and LOVES it. It is really fast, and holds a charge for miles and miles. (We run it all over Fort Wilderness and all over the parks.)
We rented a Pride Victory 9 just last December when my DH joined me unexpectedly on my extended trip at Fort Wilderness. He drove his car which will not hold his Pride 10.
The Pride 9 worked exactly like the Pride 10, but was not quite as fast. Held a charge really well. We also had it at Fort Wilderness and drove it all over there, plus the parks.
The Pride 10 is really heavy, and it's all we can do to lift it in the back of the truck. We never tried lifting the Pride 9, but it would seem like it would be lighter.
