KarenMarie,
If you do get a scooter, it should also have its warranty and a return/exchange policy and time-frame. During that "window," give it a demo under the circumstances and conditions you'll be using it.
If it's just not the right or best model for you, demo'ing could be key in determing whether to keep or switch models.
I'd test it on upgrades, doorway thresholds, grass and so on. It's important to do so with the battery fully/newly (re)charged. (A low or old charge can affect the performance.)
I did re-read my other post, and I didn't notice that I mentioned anything about, i.e., headrest, baskets/storage, visibility, and vehicle manufacturers that help with lift/retrofitting costs.
Many vehicle makers, these day, offer financial help or incentives on the costs of lifts.
I also had mine fitted with rearview mirrors and a (visibility) flag. I quickly found it annoying not to be able to see who/what may be approaching from behind.
Depending on climate (rain, fog, etc.) where you'll be using yours, will be able to help you assess which color is most ideal for your (use) area/s. Too, I don't know whether it's all makes, but that some should not be used in rainy weather due to the battery and exposure to moisture.
I've never stored mine outdoors; it just hasn't seemed like a good idea. That (storage), as well, is something to think about.
I had noted about the manufacturer's ability to perform on warranty, so I'll expand on that a bit here...
Some makers have really solid warranties. A setback is when it's stipulated that the scooter must be taken for repair as opposed to the manufacturer arranging for pick-up and a loaner (free of cost during repair time). If mine breaks down, for example: The manufacturer picks up, brings a loaner, and delivers the repaired scooter. (And... find out what happens, too, after the warranty expires.)
Also, if you travel, check out the mode of transportation's policy before travel. (Most have criteria for, i.e., batteries).
