I have a mobility scooter that simply folds down - it folds itself down to the size of a suitcase, and can easily be lifted into the boot of a car. The Quingo and those ramps are furiously expensive, and unnecessary. I’ve never tried the quingo, but it looks to have a very low ground clearance. Many shop doors have a small kerb which can trap a low mobility scooter in my experience. For town work, bigger wheels and higher ground clearance are vital. I have an electric wheelchair that does that job easily.
If you like, to avoid advertising, I’ll point you in the right direction to find the right piece of kit to fulfil the job description via PM, and a sight cheaper than the quingo.
