There are many choices. How important is budget? How important is weight? Battery life? Ease of use? Durability? Answers will differ based on your own priorities. We own two scooters. Both are easy to get in and out of the car. Mine cost nearly $3K, and has been worth every cent. BB is 34 pounds WITH battery, is fairly comfortable, battery lasts all day....no complaints. The second scooter, shared by my husband and son has a battery that doesn't last as long, but comes with two batteries. No basket, no platform on the base. Very easy to get on and off. A tiny bit heavier, and we tend to split front and back. Still very convenient, an she cost all of $500.
I'm sure she won't last as long as BB, but we've probably covered the cost in the year we've had her.
One thing you need to be aware of...you must protect the electrical connections on the rudder/handlebar AND the battery in case of rain. I carry a poncho and plastic bags like your newspaper comes in. Some carry shower caps.
Amazon actually has ponchos that can cover both you and your vehicle. Obviously, they are reusable. Good luck with your decision. I wouldn't be able to go much of anywhere without mine.
