Most carmakers have moved away from these type of cars in favour of SUVs and/or van-based MPVs. Personally, I think a van-based MPV would be the best choice for you. The interior quality of these vehicles has improved a lot in recent years, which means they look and feel more car-like than ever before. Both the Citroen Berlingo MPV and Volkswagen Caddy Life are excellent cars.

However, if you want something more car-like, you will need to find a Volkswagen Sharan or Renault Grand Scenic. However, if your wife's wheelchair is struggling to fit in the Ford Galaxy, neither of these vehicles may be suitable. And that means a van-based MPV may be your only option.
