So, after spending a very active 70+ years trying to avoid back problems, Mutha_Duke has finally been overtaken by them (two herniated discs and a spinal nerve cyst... so far...) and is really struggling with her mobility. Their current ride is an A-class which they've had for years, despite it being a horrible money pit, and even though it's fairly tall she struggles to get in and out - I'm also pretty sure that the harsh ride and hard seats are causing further discomfort although she won't admit it. For some reason they don't qualify for a mobility car, and are on a very low income, so are fairly limited in options.
I'm thinking that a older Berlingo/Kangoo/Doblo/etc/etc might be the answer, but have absolutely no knowledge of them at all. Are there any variants that should be avoided like the plague? Are any of them markedly better than the others? Are they reasonably OK to drive and comfy to be in?
Their only requirements are an autobox, power steering, and enough luggage space for a (folded) wheelchair without losing any seats. Their budget is very low, although there's some value in the A-class I guess. Any advice?
